The in_mem optimization in ext3_get_inode_loc avoids a disk read when only
the requested inode in the block group is allocated: In that case
ext3_get_inode_loc assumes that it can recreate the inode from the
in-memory inode.  This is incorrect with in-inode extended attributes,
which don't have a shadow copy in memory.  Hide the in_mem option and
clarify comments; the subsequent ea-in-inode changes the in_mem check as
required.
