[PATCH 1/2] ARM-OMAP2+: Delete an unnecessary check before the function call "omap_device_delete"

The omap_device_delete() 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.
