Subject: [PATCH] [media] cx231xx: drop condition with no effect

The if and the else code are identical - so the condition has no effect
on the effective code.
This patch removes the condition and the duplicated code.

The if and the else code are identical - so the condition has no effect.
The value of the assignment was placed into () for readability as other long
bit-wise constructs in this file also do so.

Patch was only compile tested with imx_v6_v7_defconfig
CONFIG_MEDIA_ANALOG_TV_SUPPORT=y, CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y,
CONFIG_VIDEO_CX231XX=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
