[PATCH] lib/decompressors: remove set but not used variabled 'level'

[Yu Kuai]

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.

Fixes: 7dd65feb6c60 ("lib: add support for LZO-compressed kernels")
