xhci: dbc: Make function xhci_dbc_ring_alloc() static

Browse Source 
The sparse tool complains as follows:

drivers/usb/host/xhci-dbgcap.c:422:18: warning:
 symbol 'xhci_dbc_ring_alloc' was not declared. Should it be static?

This function is not used outside ofxhci-dbgcap.c, so this commit
marks it static.

Fixes: ac286428c6 ("xhci: dbc: don't use generic xhci ring allocation functions for dbc.")
