svn commit: r356066 - head/sys/fs/nfsclient

Log:
  Fix nfsmount() so that it will return NFSERR_MINORVERMISMATCH.
  
  If nfsrpc_getdirpath() returns NFSERR_MINORVERMISMATCH, it would erroneously
  get mapped to EIO. This was not particularily harmful, but would make it
  hard for sysadmins to diagnose why an NFSv4 mount is failing.
  
  mount_nfs.c still needs to be fixed so that it does not report
  NFSERR_MINORVERMISMATCH as an unknown error 10021.
