[media] USB: Deletion of unnecessary checks before three function calls
GIT_AUTHOR_DATE=1416486805 The functions pvr2_hdw_destroy(), rc_unregister_device() and vfree() perform also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
