hw: megasas: consider 'iov_count=0' is an error in megasas_map_sgl
Currently in 'megasas_map_sgl' when 'iov_count=0' will just return
success however the 'cmd' doens't contain any iov. This will cause
the assert in 'scsi_dma_complete' failed. This is because in
'dma_blk_cb' the 'dbs->sg_cur_index == dbs->sg->nsg' will be true
and just call 'dma_complete'. However now there is no aiocb returned.
This fixes the LP#1878263:
