[libvirt] [PATCH v4 18/23] security_dac: Fix info messages when chown()-ing

Firstly, the message that says we're setting uid:gid shouldn't be
called from virSecurityDACSetOwnershipInternal() because
virSecurityDACRestoreFileLabelInternal() is calling it too.
Secondly, there are places between us reporting label restore and
us actually doing it where we can quit. Don't say we're doing
something until we are actually about to do it.
