mm/swap_slots.c: make swap_slots_cache_mutex and swap_slots_cache_enable_mutex static
The mutexes swap_slots_cache_mutex and swap_slots_cache_enable_mutex are
local to the source and do not need to be in global scope, so make them
static.
Cleans up sparse warnings:
symbol 'swap_slots_cache_mutex' was not declared. Should it be static?
symbol 'swap_slots_cache_enable_mutex' was not declared. Should it be static?
