Subject: [char-misc-next 12/27] mei: amthif: use rx_wait queue also for amthif client

From: Alexander Usyskin <alexander.usyskin@...el.com>

Switch using cl->rx_wait wait queue also for amthif, there is nothing
special about amthif in that matter in Rx flow.
The cl->wait is reserved for hbm flows and asynchronous events
