Fixes this failure: tshark: lapi.c:175: lua_settop: Assertion `(-(idx+1) <= (L->top - (func + 1))) && "invalid new top"' failed. Found using LUA 5.2 compiled with -DLUA_USE_APICHECK. Note that the value returned by luaopen_bit does not affect the size of the stack after using lua_call; if there are excess return values, then these will be dropped after calling lua_call. See http://www.lua.org/pil/26.2.html I also verified that the stack is still empty after calling all wslua_reg_module functions.
