rsu: various initialization fixes.

- Do not ignore initialization errors; call ieee80211_stop()
when initialization failed.
- Use usb_pause_mtx() instead of DELAY() while waiting for firmware
loading; this fixes system freeze during firmware startup.
- Do not execute rsu_stop() when device is powered off; fixes
'unknown board type (rfconfig=0xff)' error when the device is
reattached.

Tested with Asus USB-N10.
