Some devices can expose mw_cunits equal to 0, it can cause the creation of too small write buffer and cause performance to drop on write workloads. Additionally, write buffer size must cover write data requirements, such as WS_MIN and MW_CUNITS - it must be greater than or equal to the larger one multiplied by the number of PUs. However, for performance reasons, use the WS_OPT value to calculation instead of WS_MIN. Because the place where buffer size is calculated was changed, this patch also removes pgs_in_buffer filed in pblk structure.
