ext4: fix use-after-free race with debug_want_extra_isize
When remounting with debug_want_extra_isize, we were not performing the
same checks that we do during a normal mount. That allowed us to set a
value for s_want_extra_isize that reached outside the s_inode_size.
Fixes: e2b911c53584 ("ext4: clean up feature test macros with predicate functions")
