pf: Fix panic on unload

vnet_pf_uninit() is called through vnet_deregister_sysuninit() and
linker_file_unload() when the pf module is unloaded. This is executed
after pf_unload() so we end up trying to take locks which have been
destroyed already.

Move pf_unload() to a separate SYSUNINIT() to ensure it's called after
all the vnet_pf_uninit() calls.
