I must admit, I have no idea why we build such POSIX dependent
code as DAC driver for something such not POSIX as WIN32. Anyway,
the code which is supposed to set error is not doing that. The
proper way is to mimic what chown() does:
On error, -1 is returned, and errno is set to indicate the error.

As shown in the previous commit, @path can be NULL. However, in
that case @src->path is also NULL. Therefore, trying to "fix"
@path to be not NULL is not going to succeed. The real value of
NULLSTR() is in providing a non-NULL string for error reporting.
Well, that can be done in the error reporting without overwriting
argument.

The virSecurityDACSetOwnershipInternal() function accepts two
arguments (among others): @path and @src. The idea being that in
some cases @path is NULL and @src is not and then @path is filled
from @src->path. However, this is done in both callers already
(because of seclabel remembering/recall). Therefore, this code in
virSecurityDACSetOwnershipInternal() is dead, effectively.

The virSecurityDACSetOwnershipInternal() has two callers and in
both the private data (@priv) is obtained via
virSecurityManagerGetPrivateData(). But in case of DAC driver the
private data can never be NULL. This is because the private data
is allocated in virSecurityManagerNewDriver() according to
.privateDataLen attribute of secdriver. In case of DAC driver the
attribute is set to sizeof(virSecurityDACData).
NB, no other function within DAC driver checks for !priv.

The NVRAM label is set in qemuSecuritySetAllLabel(). There's no
need to set its label upfront. In fact, setting it twice creates
an imbalance because it's unset only once which mangles seclabel
remembering. However, plain removal of the
qemuSecurityDomainSetPathLabel() undoes the fix for the original
bug (when dynamic ownership is off then the NVRAM is not created
with cfg->user and cfg->group but as root:root). Therefore, we
have to switch to virFileOpenAs() and pass cfg->user and
cfg->group and VIR_FILE_OPEN_FORCE_OWNER flag. There's no need to
pass VIR_FILE_OPEN_FORCE_MODE because the file will be created
with the proper mode.

The 'rbd_image_spec_t' struct has two string members 'id' and
'name'. We only stole the 'name' members thus the 'id's as well as the
whole list would be leaked on success.
Restructure the code so that we copy out the image names and call
rbd_image_spec_list_cleanup on success rather than on error.
The error path is then handled by using g_autofree for 'images'.
Since we no longer have a error path after allocating the returned
string list we can completely remove its cleanup.
