AP_GPS: Fix SBF race condition on start 

Unsure what the underlying problem is, but the length of the first string in
the initilisation_blob increasing resulted in a race condition, waiting
longer before retrying the message resolves it, but we still need to identify
the underlying problem. This patch just results in the GPS working with current
configurations. Tested against AsteRx-M firmware 3.6.3
