f2fs: compress: fix to check zstd compress level correctly in mount option

Browse source

f2fs only support to config zstd compress level w/ a positive number due
to layout design, but since commit e0c1b49f5b ("lib: zstd: Upgrade to
latest upstream zstd version 1.4.10"), zstd supports negative compress
level, so that zstd_min_clevel() may return a negative number, then w/
below mount option, .compress_level can be configed w/ a negative number,
which is not allowed to f2fs, let's add check condition to avoid it.

mount -o compress_algorithm=zstd:4294967295 /dev/sdx /mnt/f2fs
