lightnvm: fix memory leak when submit fails 

commit 9778448175 upstream.

The allocated page is not released if error occurs in
nvm_submit_io_sync_raw(). __free_page() is moved ealier to avoid
possible memory leak issue.

Fixes: aff3fb18f9 ("lightnvm: move bad block and chunk state logic to core")
