ext4: Fix NULL dereference in ext4_ext_migrate()'s error handling

(cherry picked from commit 090542641de833c6f756895fc2f139f046e298f9)

This was found through a code checker (http://repo.or.cz/w/smatch.git/).
It looks like you might be able to trigger the error by trying to migrate
a readonly file system.
