net: mvpp2: fix buffers' DMA handling on RX path
Each allocated buffer, whose pointer is put into BM pool is DMA-mapped.
Hence it should be properly unmapped after usage or when removing buffers
from pool.
This commit fixes DMA handling on RX path by adding dma_unmap_single() in
mvpp2_rx() and in mvpp2_bufs_free(). The latter function's argument number
had to be increased for this purpose.
