raid5: Add R5_ReadNoMerge flag which prevent bio from merging at block layer
Because bios will merge at block-layer,so bios-error may caused by other bio which be merged into to the same request. Using this flag,it will find exactly error-sector and not do redundant operation like re-write and re-read. V0->V1:Using REQ_FLUSH instead REQ_NOMERGE avoid bio merging at block layer.
