[PATCH v3] usb: gadget: f_midi: Add checking if it need align buffer's size to an ep's maxpacketsize

Some gadget device (such as dwc3 gadget) requires quirk_ep_out_aligned_size attribute, which means it need to align the request buffer's size to an ep's maxpacketsize. Thus we add usb_ep_align_maybe() function to check if it is need to align the request buffer's size to an ep's maxpacketsize.
