net: qrtr: Force wakeups for data packets



Force a wakeup when queueing packets to a socket. This is needed to
give userspace clients a chance to run if the device is going into
system suspend. The wakeup event should force the device to abort
suspend.

The only node that should not behave this way is the SLPI node because
sensor stream race conditions cause suspend issues and power drain
issues.
