[PATCH 4/6] usb: gadget: tegra-xudc: fix the wrong mult value for HS isoc or intr

[Chunfeng Yun]

usb_endpoint_maxp() only returns the bit[10:0] of wMaxPacketSize
of endpoint descriptor, not includes bit[12:11] anymore, so use
usb_endpoint_maxp_mult() instead.
Meanwhile no need AND 0x7ff when get maxp, remove it.
