libertas: reduce command retry time
[PATCH, take 2] libertas: reduce command retry time
In the normal case, an unsuccessful command would be retried for 10*5 seconds,
or 10*10 seconds in the worst case. This patch reduces this to 3*3 seconds,
or 3*10 seconds in the worst case.
I also reduced the time it takes to start a new command downloaded.
