f2fs: compress: fix inconsistent update of i_blocks in release_compress_blocks and reserve_compress_blocks
After release a file and subsequently reserve it, the FSCK flag is set
when the file is deleted, as shown in the following backtrace:
F2FS-fs (dm-48): Inconsistent i_blocks, ino:401231, iblocks:1448, sectors:1472

For clusters of the following type, i_blocks are decremented by 1 and
i_compr_blocks are incremented by 7 in release_compress_blocks, while
updates to i_blocks and i_compr_blocks are skipped in reserve_compress_blocks.
raw node:
D D D D D D D D
after compress:
C D D D D D D D
after reserve:
C D D D D D D D
Let's update i_blocks and i_compr_blocks properly in reserve_compress_blocks.
