Modified Files:
	src/sys/nfs: nfs.h nfs_socket.c nfs_syscalls.c

Log Message:
improve nfsd locking.
- don't bother to take nfs_sndlock when doing nfsrv_rcv.
  unlike client, we never reconnect.
- nfsrv_getstream: fix the case that m_split sleeps.
- free socket in nfsrv_slpderef rather than nfsrv_zapsock.
  fix race with nfssvc_nfsd.
- while i'm here, remove NFSD_WAITING and NFSD_REQINPROG
  as they are redundant.
- some comments and assertions.
