kernel: msm_sysstats: Account DMA32 zone memory in taskstats

Browse Source 
Account DMA32 zone memory in taskstats. Since our systems will always
have atleast 32bit capable devices, ZONE DMA is most unlikely to be
enabled thus DMA32 zone info is accounted in stats->dma_nr_xxx inplace
of creating additional structure variables.
