usb: renesas_usbhs: gadget: fix spin_lock_init() for &uep->lock
This patch fixes an issue that the spin_lock_init() is not called
for almost all pipes. Otherwise, the lockdep output the following
message when we connect a usb cable using g_ncm:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
