[ 106/122] em28xx: regression fix: use DRX-K sync firmware requests on em28xx

From: Mauro Carvalho Chehab <mchehab@redhat.com>

commit 2425bb3d4016ed95ce83a90b53bd92c7f31091e4 upstream.

As em28xx-dvb will always be initialized asynchronously, there's
no need anymore for a separate thread to load the DRX-K firmware.

Fixes a known regression with kernel 3.6 with tda18271 driver
and asynchronous DRX-K firmware load.

Antti tested it with the following hardware:
Hauppauge WinTV HVR 930C
MaxMedia UB425-TC
PCTV QuatroStick nano (520e)
