[PATCH] fixes of tcp_hostcache.c

[Taku YAMAMOTO]

Greetings,

I found two calls of bcopy() in tcp_hostcache.c got the source and the
destination pointer wrongly.
# Perhaps the author got confused with memcpy(), I guess.

The fix is attached as a patch against tcp_hostcache.c as of revision 1.2.

Please review and incorporate the patch to the tree because the bug makes
hostcache useless with TCPv6 and/or brings TTCP (RFC1644) meaningless.
Especially the bug renders it unusable to use TCPv6 and TTCP together.
# To confirm this: sysctl net.inet.tcp.rfc1644=1; telnet ::1

Best regards,
Taku
