mac-address-set: Make the bt mac inverted on demand

Detecting if the mac address must be inverted means doing two resets of
the chip in a short period when the mac must be inverted.
These two resets is sometimes letting the BT chip in a state where it
does not answer for more than a minute.

Also fixes getopts string: options -w and -b don't have arguments.
