Documentation/auxiliary_bus: Clarify the release of devices from find device

Browse Source 
auxiliary_find_device() takes a proper get_device() reference on the
device before returning the matched device.

Users of this call should be informed that they need to properly release
this reference with put_device().

* This function returns a reference to a device that is 'found'
* for later use, as determined by the @match callback.
*
* The reference returned should be released with put_device().
*
* The callback should return 0 if the device doesn't match and non-zero
* if it does. If the callback returns non-zero, this function will
* return to the caller and not iterate over any more devices.
