Fix FS#12239, data abort after going from FMS to WPS.

The data abort was in find_handle() because current_handle was corrupted. This
most probably happened due to the FMS allocating Radio AA on the buffer without
resetting the buffer, corrupting buffering/playback state.

The fix is to grab buffer control explicitely.

r30308 isn't actually related, regardless of the task title.
