[LU-6566] improve sub_stripe lock/unlock

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.8.0

Description

In mdt_reint_setattr, it should only lock sub_stripes
for certain attributes, for other attributes, it only
needs to set on the master object.

In lod_object_unlock, since it already know the lock
handle, it can release the lock directly, instead of
load and holding the sub-stripe object.
