Yoshihiro Shimoda 4d599cd3a0 usb: renesas_usbhs: gadget: Fix usb_ep_set_{halt,wedge}() behavior 
According to usb_ep_set_halt()'s description,
__usbhsg_ep_set_halt_wedge() should return -EAGAIN if the IN endpoint
has any queue or data. Otherwise, this driver is possible to cause
just STALL without sending a short packet data on g_mass_storage driver,
and then a few resetting a device happens on a host side during
a usb enumaration.
