UBIFS: remove a bit of unneeded code
This is a clean-up patch which:
1. Removes explicite 'hrtimer_cancel()' after 'ubifs_wbuf_sync()' in
'ubifs_remount_ro()', because the timers will be canceled by
'ubifs_wbuf_sync()', no need to cancel them for the second time.
2. Remove "if (c->jheads)" check from 'ubifs_put_super()', because
at journal heads must always be allocated there, since we checked
earlier that we were mounted R/W, and the olny situation when
journal heads are not allocated is when mounter or re-mounted R/O.
