param_shmem: fixes for params on Snapdragon

Browse Source 
On Snapdragon we can't yet use the "used" mask for parameters and
therefore need to send all of them down to the ground station. All
params were set to used in an earlier commit but the count and index
function didn't reflect this change. This is fixed now, therefore we can
successfully receive all params in QGC.
