This change ensures that PM reference is always get during packet
queueing and released either after queuing completion (RX) or once
the buffer has been consumed (TX). This guarantees proper update for
underlying MHI controller runtime status (e.g. last_busy timestamp)
and prevents suspend to be triggered while TX packets are flying,
or before we completed update of the RX ring.

Since M3 can be entered/exited quite a lot when used for runtime PM,
keep the mhi suspend/resume transitions quiet.

This could be "Waiting for M3 completion". But I'll change it while
applying.
