ext4: make __es_remove_extent() check extent status

Browse source

Currently, __es_remove_extent() unconditionally removes extent status
entries within the specified range. In order to prepare for extending
the ext4_es_cache_extent() function to cache on-disk extents, which may
overwrite some existing short-length extents with the same status, allow
__es_remove_extent() to check the specified extent type before removing
it, and return error and pass out the conflicting extent if the status
does not match.
