[char-misc 3.10] mei: init: Flush scheduled work before resetting the device

[Tomas Winkler]

From: Samuel Ortiz <sameo@xxxxxxxxxxxxxxx>

Flushing pending work items before resetting the device makes more
sense than doing so afterwards. Some of them, like e.g. the NFC
initialization one, find themselves with client IDs changed after
the reset, eventually leading to trigger a client.c:mei_me_cl_by_id()
warning after a few modprobe/rmmod cycles.
