Currently

In non-destructive mode testing with multiple pattern, only first pattern skips known bad blocks, the following pattern will not skip.
In write mode, the known bad blocks from input files and previous test pass will not be skipped
After skipped known bad blocks, the performance decreased until find a new bad block

This PR will

Make multi-pattern non-destructive test skip known bad blocks from input file and previous test correctly
Implement the known bad block logic in write mode test
Fix the performance issue with known bad blocks
