Modified the event coalescing code for iSCSI offload to combat both corner cases and optimize performance as follows: 1. Added mechanism to loop back a second time to process any leftover CQEs that was generated by the hardware during the time the driver is busy processing previous CQEs in the bh. This not only helps the performance but also fixes the corner case when no more CQEs are being generated in the pipeline; so those leftover CQEs will get a a chance to be processed. 2. Added ARM_CQE_FP to distinguish between fast path arming versus slow path arming. This change will guarantee that the CQEs will always get a chance to be re-armed during fast path completions. 3. Removed the inline event coalescing division for perf optimization. Also fixed a division-by-zero error when the event_coal_div module param was set to 0. 4. Changed the default SQ WQEs size from 256 to 128 to match chip default. 5. Changed the cmd_per_lun from 32 to 24.
