KVM: MIPS: Drop @max param from mmu_topup_memory_cache()
Replace the @max param in mmu_topup_memory_cache() and instead use
ARRAY_SIZE() to terminate the loop to fill the cache. This removes a
BUG_ON() and sets the stage for moving MIPS to the common memory cache
implementation.
No functional change intended.
