Make sure the rx_allocator worker is canceled before running the
rx_init routine. rx_init frees and re-allocates all rxb's pages. The
rx_allocator worker also allocates pages for the used rxb's. Running
rx_init and rx_allocator simultaniously causes a kernel panic. Fix
that by canceling the work in rx_init.
