====================
rxrpc: Fixes

Here are some miscellaneous fixes for AF_RXRPC:

 (1) Remove a duplicate variable initialisation.

 (2) Fix one of the checks made when we decide to set up a new incoming
     service call in which a flag is being checked in the wrong field of
     the packet header.  This check is abstracted out into helper
     functions.

 (3) Fix RTT gathering.  The code has been trying to make use of socket
     timestamps, but wasn't actually enabling them.  The code has also been
     recording a transmit time for the outgoing packet for which we're
     going to measure the RTT after sending the message - but we can get
     the incoming packet before we get to that and record a negative RTT.

 (4) Fix the emission of BUSY packets (we are emitting ABORTs instead).

 (5) Improve error checking on incoming packets.

 (6) Try to fix a bug in new service call handling whereby a BUG we should
     never be able to reach somehow got triggered.  Do this by moving much
     of the checking as early as possible and not repeating it later
     (depends on (5) above).

 (7) Fix the sockopts set on a UDP6 socket to include the ones set on a
     UDP4 socket so that we receive UDP4 errors and packet-too-large
     notifications too.

 (8) Fix the distribution of errors so that we do it at the point of
     receiving an error in the UDP callback rather than deferring it
     thereby cutting short any transmissions that would otherwise occur in
     the window.
