Description

Following up LU-6528.
We keep fs capa for mdt_reint_getattr() but we should do the same for mdt_getattr_name().

The logic introduced by LU-6528 was removed by LU-7199 commit
2aea469a3a, this should be addressed.

in old_init_ucred_common() we could still fail the identity check if we don't have a valid fsuid, make sure that won't happen when we have raised capability.
