[PATCH] media: omap2: omapfb: fix bugon.cocci warnings

From: kbuild test robot

drivers/video/fbdev/omap2/omapfb/dss/dss_features.c:895:2-5: WARNING: Use BUG_ON instead of if condition followed by BUG.
Please make sure the condition has no side effects (see conditional BUG_ON definition in include/asm-generic/bug.h)

Use BUG_ON instead of a if condition followed by BUG.

Semantic patch information:
This makes an effort to find cases where BUG() follows an if
condition on an expression and replaces the if condition and BUG()
with a BUG_ON having the conditional expression of the if statement
as argument.

Please take the patch only if it's a positive warning. Thanks!
