kernel - Change mbuf allocation in tapwrite/tunwrite path to blocking

* Tapwrite and tunwrite are called via userland, a blocking mbuf allocation
  is perfectly acceptable here and avoids dropping packets unnecessarily.

* Fixes numerous spurious packet drops when using TAP or TUN, for example
  with openvpn.

* Minor code cleanup in if_tap.c
