Remove spurious call to unix_physmem_init(...)
It turns out that unix_physmem_init(...) has been effectively disabled for a very long time. The vnet library supplied a weak symbol override for the vlib_app_physmem_init(...) which returned 1, meaning "do nothing." When we switched libvnet.a -> libvnet.so, the symbol override stopped working. Presto: unix_physmem_init(...) romps all over the data set up by vlib_buffer_pool_create(...), leading to ASSERT failures and/or bus errors, but only when using worker threads. Even then, the failure depended in some complicated way on library dynamic load order. We should remove .../vlib/vlib/unix/physmem.c entirely once we're sure we'll never want it back.
