When shutdown(s, SHUT_RD) is called, it calls sorflush(), which uses
bzero to wipe out the socket buffer.  However, this is not the right
thing to do, as some state may need to be kept (SB_SEL, SB_AIO, SB_KNOTE).
In particular, erasing the si_note entry will cause a panic in
filt_sordetach() later, when the system attempts to remove the knote
from the SLIST.

Add a workaround which leaves the si_note field alone.  The real fix
is to only clear out those fields which need to be reset, rather than
using bzero() to swat everything.  However, this close to -release, a
minimal fix was chosen in order to keep changes to a minimum.
