f2fs: fix NULL pointer dereference in f2fs_submit_page_write()

It is possible that other threads have added this fio to io->bio and submitted the io->bio before entering f2fs_submit_page_write(). At this point io->bio = NULL. If is_end_zone_blkaddr(sbi, fio->new_blkaddr) of this fio is true, then an NULL pointer dereference error occurs at bio_get(io->bio). The original code for determining zone end was after "out:", which would have missed some fio who is zone end. I've moved this code before "skip:" to make sure it's done for each fio.

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.

f2fs: compress: fix to avoid inconsistence bewteen i_blocks and dnode

[ Upstream commit 54607494875edd636aff3c21ace3ad9a7da758a9 ] In reserve_compress_blocks(), we update blkaddrs of dnode in prior to inc_valid_block_count(), it may cause inconsistent status bewteen i_blocks and blkaddrs once inc_valid_block_count() fails.
