avformat/hls: reduce default max reload to 3

Browse Source 
The 1000 did result in the appearance of a never ending reload loop

The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"

Trying to reload 3 times seems a better default than 1000 given these
durations
