fixed the problem with messages not getting through

the problem had nothing to do with being your own pid, it was instead
a problem with IPC$ connections not being registered in the
connections database and an incorrect test for -1 in the messaging
code.

These changes also mean that IPC$ shares now show up in
smbstatus. That is probably a good thing.
