MIPS: mm: Remove redundant drop_mmu_context() cpu argument
The drop_mmu_context() function accepts a cpu argument, but it implicitly expects that this is always equal to smp_processor_id() by allocating & configuring an ASID on the local CPU when the mm is active on the CPU indicated by the cpu argument. All callers do provide the value of smp_processor_id() to the cpu argument. Remove the redundant argument and have drop_mmu_context() call smp_processor_id() itself, making it clearer that the cpu variable always represents the local CPU.
