UPSTREAM: zsmalloc: fixup trivial zs size classes value in comments

Browse Source 
(cherry-pick from commit 7eb52512a977854eca51d9b692c2f3be8a0e5eeb)

According to calculation, ZS_SIZE_CLASSES value is 255 on systems with 4K
page size, not 254.  The old value may forget count the ZS_MIN_ALLOC_SIZE
in.

This patch fixes this trivial issue in the comments.
