        src/sys/dev/usb: if_urtw.c if_urtwreg.h

Log Message:
Fix error handling, to prevent kernel crashes when detaching an urtw0
device. Also, fail safely if we didn't recognize the RF chip, to prevent
kernel crashes at attach time. Note that other panics are there, maybe
they also should be removed.
