f_qdss: allow USB enumeration if speed is full speed mode



Currently USB QDSS driver fails set_alt() if enumerated speed
is full speed as USB BAM can't support full speed mode. To
allow other USB interfaces to work in full speed, this change
doesn't fail USB QDSS set_alt() although it doesn't enable
USB QDSS related endpoints and queue any endless transfer.
