From: Quinn Tran <quinn.tran@cavium.com>

When driver is unloaded, all sessions are torn down, all
commmands are flushed, chip is reset to ensure there is
no knowledge of target mode in ISP. The irq_cmd_count field
was used to make sure all commands are processed on top of that.
The irq_cmd_count is now redundant and not needed.
