Instead of duplicating queuing procedure in mhi_queue_dma(),
mhi_queue_buf() and mhi_queue_skb(), add a new generic mhi_queue()
as common helper.
Note that the unified mhi_queue align pm_lock locking on mhi_queue_buf
behavior, taking it with irqsave variant (vs _bh for former queue_skb
and queue_dma version).

Instead of duplicating queuing procedure in mhi_queue_dma(),
mhi_queue_buf() and mhi_queue_skb(), add a new generic mhi_queue()
as common helper.
Note that the unified mhi_queue align pm_lock locking on mhi_queue_buf
behavior, taking it with irqsave variant (vs _bh for former queue_skb
and queue_dma version).
