security_dac: Don't check for !priv in virSecurityDACSetOwnershipInternal()
security_dac: Don't check for !priv in virSecurityDACSetOwnershipInternal()

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.
