target/ppc: do not call hreg_compute_hflags() in helper_store_mmcr0()
MMCR0 writes will change only MMCR0 bits which are used to calculate
HFLAGS_PMCC0, HFLAGS_PMCC1 and HFLAGS_INSN_CNT hflags. No other machine
register will be changed during this operation. This means that
hreg_compute_hflags() is overkill for what we need to do.

pmu_update_summaries() is already updating HFLAGS_INSN_CNT without
calling hreg_compure_hflags(). Let's do the same for the other 2 MMCR0
hflags.
