Subject: [char-misc-next 1/2] mei: don't use wake_up_interruptible for wr_ctrl

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

wr_ctrl waiters are none interruptible, so should be waken up
with call to wake_up and not to wake_up_interruptible.

This fixes commit:
7ff4bdd ("mei: fix waiting for wr_ctrl for corner cases.")
