[PATCH] at76c50x-usb: Supply additional parameters to at76_start_monitor scan request

[Jason Andryuk]

For my Linksys WUSB11 at76c503-i3861 device, scanning fails without
probe_delay, min_channel_time, and max_channel_time specified for the
scan request.  These values were found by checking scan requests from
the at76_usb driver.

Prior to this patch, the driver did not produce any scan results on my device.

This patch was whitespace-damaged.  I've manually fixed it, but please
adjust your mailer appropriate for any future patches...

Thanks,

John
