cluster/afr: Fix incorrect reporting of gfid & type mismatch
Problems:
1. When checking for type and gfid mismatch, if the type or gfid
is unknown because of missing gfid handle and the gfid xattr
it will be reported as type or gfid mismatch and the heal will
not complete.
2. If the source selected during entry heal has null gfid the same
will be sent to afr_lookup_and_heal_gfid(). In this function when
we try to assign the gfid on the bricks where it does not exist,
we are considering the same gfid and try to assign that on those
bricks. This will fail in posix_gfid_set() since the gfid sent
is null.
Fix:
If the gfid sent to afr_lookup_and_heal_gfid() is null choose a
valid gfid before proceeding to assign the gfid on the bricks
where it is missing.
In afr_selfheal_detect_gfid_and_type_mismatch(), do not report
type/gfid mismatch if the type/gfid is unknown or not set.
