[PATCH -next] Bluetooth: btusb: Fix the application of sizeof to pointer

[PATCH -next] Bluetooth: btusb: Fix the application of sizeof to pointer

[Yang Li]

sizeof() when applied to a pointer typed expression gives the size of
the pointer.

Clean up coccicheck warning:
./drivers/bluetooth/btusb.c:2210:36-42: ERROR: application of sizeof to
pointer
