Silby's patch to fix this was approved by re@ this morning, should go into
the tree shortly. Basically, the assertion is slightly too agressive as
some callers into BPF "mock up" mbufs to hold data submitted to BPF. No
doubt this will get cleaned up, but in the mean time the fix is simply to
remove the assertion.
