Lua: allow creating TVBs after calling other (Lua) dissectors.

Don't set `lua_tvb` (or any of the other global variables) to NULL after a
Lua dissector is called: it's possible that the caller is also a Lua dissector
which may want/need that (global) variable to still be set (to the value it
had before the sub-dissector was called).

This fixes the problem reported in:
https://ask.wireshark.org/questions/56110/lua-error-tvbs-can-only-be-created-and-used-in-dissectors

Making these variables not be a globals (as suggested at the top of
init_wslua.c) might be a better solution--for another day.
