Jiri Kosina 07c6338acb HID: sony: remove duplicate NULL check before calling usb_free_urb() 
[ Upstream commit b328dd02e1 ]

usb_free_urb() does the NULL check itself, so there is no need to duplicate
it prior to calling.

Reported-by: kernel test robot <lkp@intel.com>
Fixes: e1cd4004cd ("HID: sony: Fix a potential memory leak in sony_probe()")
