It is more lucky that kernel crash does not happen, since we test the
bi_pool in function __bio_clone_fast. Now bi_flags is used to flag the
idx, so it is incorrect to test the bi_pool.
For now, the bio in function __bio_clone_fast may have its own bvec, if
the caller is bio_clone_fast.
Removing the test to fix this issue.
