Subject[PATCH] f2fs: compress: fix to set zstd compress level correctly
Date
As 5kft reported in [1]:

set_compress_context() should set compress level into .i_compress_flag
for zstd as well as lz4hc, otherwise, zstd compressor will still use
default zstd compress level during compression, fix it.

Fixes: 3fde13f817e2 ("f2fs: compress: support compress level")
