uwb/whci: Delete an unnecessary check before the function call “umc_device_unregister”

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

The umc_device_unregister() 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.
