f2fs: compress: fix to check zstd compress level correctly in mount option
[ Upstream commit e39602da752cd1d0462e3fa04074146f6f2803f6 ]
f2fs only support to config zstd compress level w/ a positive number due
to layout design, but since commit e0c1b49f5b67 ("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
Fixes: 00e120b5e4b5 ("f2fs: assign default compression level")
