Filesystem goes to read-only after continuous error injection because RQE was handled in deferred context, leading to mismatch between CQE and RQE. Specifically, this patch makes the following changes: - Process the RQE with CQE in interrupt context, before putting it into the work queue. - Producer and consumer indices are also updated in the interrupt context to guarantee the the order of processing.
