usb: gadget: udc: renesas_usb3: fix deadlock by spinlock
commit 067d6fdc558d2c43f0bfdc7af99630dd5eb08dc5 upstream.
This patch fixes an issue that this driver is possible to cause
deadlock by double-spinclocked in renesas_usb3_stop_controller().
So, this patch removes spinlock API calling in renesas_usb3_stop().
(In other words, the previous code had a redundant lock.)
