[PATCH][usb-next] usb: xhci: make function xhci_dbc_free_req static

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Function xhci_dbc_free_req is local to the source and does not need to
be in global scope, so make it static.

Cleans up sparse warning:
symbol 'xhci_dbc_free_req' was not declared. Should it be static?
