        sys/netinet6/frag6.c: revision 1.76

frag6: don't use spin mutex for frag6_lock

frag6_lock is held during sending a packet (icmp6_error), so we must
not use a spin mutex because we can acquire sleep locks on sending
a packet.

Also we don't need to use spin mutex for frag6_lock anymore because
frag6_lock is now not used from hardware interrupt context.
