winbind: Make wb_sids2xids_recv work on an array

winbind: Make wb_sids2xids_recv work on an array

The trigger for this is that Coverity got confused by the dual use of &xid
as an array with the implicit length equality between wb_sids2xids_send
and the array passed in to wb_sids2xids_recv for the result.

I don't want to start doing things just for the Coverity scan, but this
makes the code clearer to me by removing this implicit expected array
length equality.
