f2fs: fix extent corrupotion during directIO in LFS mode
In LFS mode, por_fsstress testcase reports a bug as below:
[ASSERT] (fsck_chk_inode_blk: 931) --> ino: 0x12fe has wrong ext: [pgofs:142, blk:215424, len:16]
Since commit f847c699cff3 ("f2fs: allow out-place-update for direct
IO in LFS mode"), we start to allow OPU mode for direct IO, however,
we missed to update extent cache in __allocate_data_block(), finally,
it cause extent field being inconsistent with physical block address,
fix it.
Fixes: f847c699cff3 ("f2fs: allow out-place-update for direct IO in LFS mode")
