        src/sys/net: pfil.c

Log Message:
Add curlwp_bind

It is necessary for example when we use tun(4). Without it the following
panic occurs:

  panic: kernel diagnostic assertion "(kpreempt_disabled() || cpu_softintr_p() || ISSET(curlwp->l_pflag, LP_BOUND))" failed: file "/usr/src/sys/kern/subr_psref.c", line 291 passive references are 
CPU-local, but preemption is enabled and the caller is not in a softint or CPU-bound LWP
  Backtrace:
