UBIFS: fix LEB list freeing
When freeing the c->idx_lebs list, we have to release the LEBs as well, because we might be called from mount to read-only mode code. Otherwise the LEBs stay taken forever, which may cause problems when we re-mount back ro RW mode. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
