121 ↗	(On Diff #61245)	Why did you change the level?

Include zutil.h instead of zlib.h in order to pick up OS_CODE and DEF_MEM_LEVEL.

sys/kern/subr_compressor.c
121 ↗	(On Diff #61245)	This changeset was brought from my initial changeset. Back in that time, due to some API name conflict and few others, I couldn't include zutil.h. Our zlib migration committed in CURRENT doesn't have this restriction and I was able to revert back.
