TriggerImmediateQuery does not set mLastProvider (GenericOTARequestorDriver)

[harsha-rajendran]

Problem

OTARequestor::TriggerImmediateQuery() does not set the mLastUsedProvider (part of the GenericOTARequestorDriver), before triggering a QueryImage. This might result in the same provider being used for the next OTA "re-attempt".

Proposed Solution

Update the mLastUsedProvider in the OTARequestorDriverSendQueryImage(), perhaps? Doing this might be out of the function scope, however, so another option might be to add a new pre-SendImageQuery() in the driver?
