[PATCH v2 12/12] nvmet: use bio_chain_and_submit to simplify bio chaining

[zhangshida]

From: Shida Zhang <zhangshida at kylinos.cn>

Replace repetitive bio chaining patterns with bio_chain_and_submit.
Note that while the parameter order (prev vs new) differs from the
original code, the chaining order does not affect bio chain
functionality.
