[PATCH 1/5] zram: Fix sparse warnings

[Nitin Gupta <ngupta@vflare.org>]

Fixes sparse warning:
zram_drv.c:666:6: warning: symbol 'zram_slot_free_notify' was not
declared. Should it be static?

Also, max_zpage_size is now size_t just to be consistent with data-type
of other variables maintaining sizes of various kinds.
