Destroy the dynamic rule zone in the event that we fail to insert the
initial default rule.

- Change the return type for init_tables from void to int so we can propagate
  errors from rn_inithead back to the ipfw initialization function.
- Check return value of rn_inithead for failure, if table allocation has
  failed for any reason, free up any tables we have created and return ENOMEM
- In ipfw_init check the return value of init_tables and free up any mutexes or
  UMA zones which may have been created.
- Assert that the supplied table is not NULL before attempting to dereference.

This fixes panics which were a result of invalid memory accesses due to failed
table allocation. This is an issue mainly because the R_Zalloc function is a
malloc(M_NOWAIT) wrapper, thus making it possible for allocations to fail.
