Subject: lib/decompressors: remove set but not used variabled 'level'
Fixes gcc '-Wunused-but-set-variable' warning:
lib/decompress_unlzo.c:46:5: warning: variable `level' set but
not used [-Wunused-but-set-variable]
It is never used and so can be removed.
Link: https://lkml.kernel.org/r/20210514062050.3532344-1-yukuai3@xxxxxxxxxx
Fixes: 7dd65feb6c60 ("lib: add support for LZO-compressed kernels")
