fix HTTP download crash (on 404)

Browse source 
change parameter type to match CURL lib

(prevents crash on HTTP download)


example

test server:
q2.bot.nu:27912

server config:
set sv_downloadserver "https://quake2.pages.dev/"
map DEBEQUA2


Client connects, and three files added to queue:

HTTP download: /.filelist - Queued
HTTP download: /maps/DEBEQUA2.filelist - Queued
HTTP download: maps/DEBEQUA2.bsp - Queued


 from URL:
https://quake2.pages.dev/.filelist		- no file
https://quake2.pages.dev/maps/DEBEQUA2.filelist	- no file
https://quake2.pages.dev/maps/DEBEQUA2.bsp	- exists

when 404 response received for '.filelist' file,
CL_HTTP_Recv() is called and uses wrong file length in malloc()


one of tests:

==43024==ERROR: AddressSanitizer: requested allocation size 0x8000000000000000 (0x8000000000001000 after adjustments for alignment, red zones etc.) exceeds maximum supported size of 0x10000000000 (thread T0)
