IRQF_ONESHOT is found to mask HBA generated interrupts when thread_fn is running. As a result, some EQEs/CQEs miss timely processing resulting in SCSI layer attempts to abort commands due to io_timeout. Abort CQEs are also not processed leading to the observations of hangs and spam of "0748 abort handler timed out waiting for aborting I/O" log messages. Remove the IRQF_ONESHOT flag. The cmpxchg and xchg atomic operations on lpfc_queue->queue_claimed already protect potential parallel access to an EQ/CQ should the thread_fn get interrupted by the primary irq handler.
