usb: early: xhci-dbc: Fix a potential out-of-bound memory access
If xdbc_bulk_write() fails, the values in 'buf' can be anything. So the
string is not guaranteed to be NULL terminated when xdbc_trace() is called.
Reserve an extra byte, which will be zeroed automatically because 'buf' is
a static variable, in order to avoid troubles, should it happen.
Fixes: aeb9dd1de98c ("usb/early: Add driver for xhci debug capability")
