net: ipa: introduce gsi_channel_trans_idle()
Create a new function that returns true if all transactions for a
channel are available for use.
Use it in ipa_endpoint_replenish_enable() to see whether to start
replenishing, and in ipa_endpoint_replenish() to determine whether
it's necessary after a failure to schedule delayed work to ensure a
future replenish attempt occurs.
