MINOR: lua: Stop using the lua txn in hlua_http_get_headers()

In this function, the lua txn was only used to test if the HTTP transaction is
defined. But it is always used in a context where it is true. So, the lua txn
can be removed from the function argument list.

This patch is mandatory to allow the support of the filters written in lua.
