video: fbdev-OMAP2: Deletion of unnecessary checks before the function call “i2c_put_adapter” 

Author: Markus Elfring <elfring@users.sourceforge.net>

The i2c_put_adapter() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
