qcacmn: change minimum buffers in rxdma monitor buffer ring

With the init/de-init FR we set the minimum buffers
needed in monitor buffer ring to be 8, because the low
threshold by FW is set to 32 the MPDU TLVs are not DMA'd
to monitor status ring, this resulted in NAC feature
regressed. hence changing it from 8 to 64
