[PATCH v2 3/5] zstd: move ZSTD_MAX_CLEVEL to zstd_lib.h

[Haoqin Huang]

From: Haoqin Huang <haoqinhuang@xxxxxxxxxxx>

Move ZSTD_MAX_CLEVEL from lib/zstd/compress/clevels.h to
include/linux/zstd_lib.h so that external users (e.g. the zram
zstd backend) can reference it alongside ZSTD_TARGETLENGTH_MAX
to define a valid level range.
