net: ipa: track allocated transactions with an ID
Transactions for a channel are now managed in an array, with a free
transaction ID indicating which is the next one free.
Add another transaction ID field to track the first element in the
array that has been allocated. Advance it when a transaction is
committed (because that is when that transaction leaves allocated
state).
Temporarily add warnings that verify that the first allocated
transaction tracked by the ID matches the first element on the
allocated list, both when allocating and committing a transaction.
