John Baldwin ac695ab41b - Fix ncp_poll() to not panic if the socket doesn't have any pending data.
We have to adjust curthread's state enough so that it appears to be
  in a poll(2) or select(2) call so that selrecord() will work and then
  teardown that state after calling sopoll().
- Fix some minor nits in nearby ncp_sock_rselect() and in the identical
  nbssn_rselect() function in the netsmb code:
  - Don't call nb_poll()/ncp_poll() now that ncp_poll() already fakes up
    poll(2) state since the rselect() functions already do that.  Just
    invoke sopoll() directly.
  - To make things slightly more intuitive, store the results of sopoll()
    in a new 'revents' variable rather than 'error' since that's what
    sopoll() actually returns.
  - If the requested timeout time has been exceeded by the time we get
    ready to block, then return EWOULDBLOCK rather than 0 to signal a
    timeout as this is what the calling code expects.
