[media] ite-cir: finish tx before suspending 

Continuing with IR transmit after resuming from suspend seems fairly
useless, given that the only place we can actually end up suspending is
after IR has been send and we're simply mdelay'ing. Lets simplify the
resume path by just waiting on tx to complete in the suspend path, then
we know we can't be transmitting on resume, and reinitialization of the
hardware registers becomes more straight-forward.
