ext4: remove an unneeded NULL check in __ext4_check_dir_entry()
We dereference "bh" unconditionally a couple lines down to find "by->b_size". This function is never called with a NULL "bh" so I have removed the check. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
