Support injecting data corruption for processing read/write I/O.
Add two parameters, corrupt_offset and corrupt_value, and an error
type corrupt_data.
For write I/O, inject data corruption before submitting write I/O
to the underlying bdev. For read I/O, inject data corruption after
read I/O successfully returned.
Cause the data corruption by xoring the value at the corrupt_offset
with the corrupt_value. corrupt_value is required to be non-zero to
cause data corruption necessarily.
