[PATCH RFC] [media] dib0700: remove redundant else

[Nicholas Mc Guire]

The if and else are identical and can be consolidated here.

Fixes: commit 91be260faaf8 ("[media] dib8000: Add support for Mygica/Geniatech S2870")

Problem found by coccinelle script

Based only on reviewing this driver it seems that the dib0090_config
is not an array and thus this is a cut&past bug - but not having access
to the driver I can not say.  Other cases that have the
conditioning on (adap->id == 0) e.g. dib7070p_dib0070 actually have
a config array (dib7070p_dib0070_config[]). So the if/else here most
likely is unnecessary.

The patch is actually a partial revert of commit 91be260faaf8 ("[media]
dib8000: Add support for Mygica/Geniatech S2870") where this if/else
was deliberately introduced but without any specific comments.

This needs a review by someone that has access to the details of the driver.

Patch was compile tested with: x86_64_defconfig + CONFIG_MEDIA_SUPPORT=m,
CONFIG_MEDIA_USB_SUPPORT=y, CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y,
CONFIG_DVB_USB=m, CONFIG_DVB_USB_V2=m, CONFIG_MEDIA_RC_SUPPORT=y,
CONFIG_DVB_USB_DIB0700=m

Patch is against 4.8.0 (localversion-next is -next-20161006)
