xHCI: fix wMaxPacketSize mask

USB2.0 spec 9.6.6 says: For all endpoints, bit 10..0 specify the maximum
packet size(in bytes).

So the wMaxPacketSize mask should be 0x7ff rather than 0x3ff.

This patch should be queued for the stable tree.  The bug in
xhci_endpoint_init() was present as far back as 2.6.31, and the bug in
xhci_get_max_esit_payload() was present when the function was introduced
in 2.6.34.
