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.
