xfs: refactor zone reset handling

Include the actual bio submission in the common zone reset handler to
share more code and prepare for adding error injection for zone reset.

Note the I plan to refactor the block layer submit_bio_wait and
bio_await_chain code in the next merge window to remove some of the
code duplication added here.
