libertas: fix command timeout after firmware failure

[David Woodhouse]

From: Brian Cavagnolo <brian at cozybit.com>

This is a fix for OLPC ticket #6586: "SCAN command fails, timer doesn't
fire". In fact, the timer was firing; the problem was that the dnld_sent
state variable was not being updated after the timer expired, so
lbs_execute_next_command was not being called.
