f2fs: zone: fix to wait completion of last bio in zone correctly
[ Upstream commit 536af8211586af09c5bea1c15ad28ddec5f66a97 ]
It needs to check last zone_pending_bio and wait IO completion before
traverse next fio in io->io_list, otherwise, bio in next zone may be
submitted before all IO completion in current zone.
