qcacld-3.0: Cache roam triggers when roaming is in progress

When roaming is in progress, if the roam control vendor command
is received to update the roam triggers, the command is rejected
but the trigger bitmap value is not cached at the driver.
This causes old roam trigger values to be updated in the next RSO
command.

Cache the roam trigger bitmap in mlme when roaming is in
progress.
