[PATCH 1/5] MdeModulePkg/UsbBusDxe: log warning message at DEBUG_WARN level

[Laszlo Ersek <lersek@redhat.com>]

"UsbSelectConfig: failed to connect driver %r, ignored" is an error
message, but it states at once that the error condition will not affect
the control flow. Degrade the report to DEBUG_WARN.
