MIPS: mm: Remove redundant get_new_mmu_context() cpu argument
get_new_mmu_context() accepts a cpu argument, but implicitly assumes
that this is always equal to smp_processor_id() by operating on the
local CPU's TLB & icache.
Remove the cpu argument and have get_new_mmu_context() call
smp_processor_id() instead.
