[net PATCH] net: sched: fix act_ipt for LOG target

[Phil Sutter <psutter@redhat.com>]

From: Phil Sutter <phil@nwl.cc>

Before calling the destroy() or target() callbacks, the family parameter
field has to be initialized. Otherwise at least the LOG target will
refuse to work and upon removal oops the kernel.
