There are a few places where a variable is VIR_FREE()-d and then
explicitly set to NULL. This is not necessary since VIR_FREE()
does that for us.

In testDomainSetBlockIoTune() the info.group_name is strdup()-ed
and just after the whole @info structure is passed to
virDomainDiskSetBlockIOTune() the @group_name member is set to
NULL. This creates a memleak, because
virDomainDiskSetBlockIOTune() creates its own copy of the string.

The idea behind virNWFilterBindingObjNew() is to create and
return an object of virNWFilterBindingObjClass class. The class
is virObjectLockable (and the corresponding
_virNWFilterBindingObj structure has virObjectLockable parent).
But for some reason plain virObjectNew() is called. This is wrong
because the mutex in the parent is left uninitialized.
Next, the returned object is not locked. This is wrong because in
some cases the returned object is added onto a list of bindings
and then passed to virNWFilterBindingObjEndAPI() which unlocks it
right away. This is potentially dangerous because we might just
have unlocked the object for another thread.
