[PATCH] http.c: Spell the null pointer as NULL

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit 1bbcc224 ("http: refactor options to http_get_*", 28-09-2013)
changed the type of final 'options' argument of the http_get_file()
function from an int to an 'struct http_get_options' pointer.
However, it neglected to update the (single) call site. Since this
call was passing '0' to that argument, it was (correctly) being
interpreted as a null pointer. Change to argument to NULL.

Noticed by sparse. ("Using plain integer as NULL pointer")

Hi Junio,

This is a repost of:

I suspect that this simply fell through the cracks ... (if not,
please let me know ;-)

ATB,
Ramsay Jones
