HID: usbhid: Simplify code in hid_submit_ctrl()
This patch makes a small simplification to the code in
hid_submit_ctrl(). The test for maxpacket being > 0 is unnecessary,
because endpoint 0 always has a maxpacket value which is >= 8.
Furthermore, endpoint 0's maxpacket value is always a power of 2, so
instead of open-coding the round-to-next-multiple computation we can
call the optimized round_up() routine.
