David Laight 4d2fe0addc net: sctp: Fix negotiation of the number of data streams. 
[ Upstream commit ab921f3cdb ]

The number of output and input streams was never being reduced, eg when
processing received INIT or INIT_ACK chunks.
The effect is that DATA chunks can be sent with invalid stream ids
and then discarded by the remote system.

Fixes: 2075e50caf ("sctp: convert to genradix")
