afr: handle bad objects during lookup/inode_refresh
If an object (file) is marked bad by bitrot, do not consider the brick
on which the object is present as a potential read subvolume for AFR
irrespective of the pending xattr values.
Also do not consider the brick containing the bad object while
performing afr_accuse_smallfiles(). Otherwise if the bad object's size
is bigger, we may end up considering that as the source.
