Re: [libvirt] [PATCH 22/24] maint: improve VIR_ERR_INVALID_DOMAIN_SNAPSHOT usage

The existing check of domain snapshots validated that they point to a domain, but did not validate that the domain points to a connection, even though any errors blindly assume the connection is valid. For consistency with previous patches, continue the trend of using a common macro. For now, we don't need virCheckDomainSnapshotGoto(). * src/datatypes.h (virCheckDomainSnapshotReturn): New macro. (VIR_IS_SNAPSHOT, VIR_IS_DOMAIN_SNAPSHOT): Drop unused macros. * src/libvirt.c: Use macro throughout. (virLibDomainSnapshotError): Drop unused macro.
