[PATCH] Fix two problems with multiple concurrent nfs/tcp connects.

1/ connect requests would be get lost...
  As the comment at the top of svcsock.c says when discussing
  SK_CONN:
 *		after a set, svc_sock_enqueue must be called.

  We didn't and so lost conneciton requests.

2/ set the max accept backlog to a more reasonable number to cope
   with bursts of lots of connection requests.
