Introduce the new block IO status BLK_STS_DURATION_LIMIT for LLDDs to

serious hardware related errors.

What makes exceeding the duration limit different from an I/O timeout 
(BLK_STS_TIMEOUT)? Why is it important to tell the difference between an 
I/O timeout and exceeding the command duration limit?

Thanks,
