All references for frag pages that are obtained in tx_sync_info_get()
should be released.
Release usually occurs in the corresponding CQE of the WQE.
In error flows, not all fragments have a WQE posted for them, hence
no matching CQE will be generated.
For these pages, release the reference in the error flow.
