[STACK] >3k call path in ncpfs

[Jörn Engel]

ncpfs has a few stack-hungry functions.  Could you try to put
ncp_ioctl() and/or ncp_conn_logged_in() on a diet?  Example call path
is below.

stackframes for call path too long (3004):
    size  function
     720  ncp_ioctl
     616  ncp_conn_logged_in
      24  ncp_lookup_volume
       0  ncp_request2
     164  sock_sendmsg
