More aggressively assert that db_mtx protects db.db_data
db.db_mtx must be held any time that db.db_data is accessed.  All of
these functions do have the lock held by a parent; add assertions to
ensure that it stays that way.

See https://github.com/openzfs/zfs/discussions/17118

* Refactor dbuf_read_bonus to make it obvious why db_rwlock isn't
required.

* Refactor dbuf_hold_copy to eliminate the db_rwlock
Copy data into the newly allocated buffer before assigning it to the db.
That way, there will be no need to take db->db_rwlock.

* Refactor dbuf_read_hole
In the case of an indirect hole, initialize the newly allocated buffer
before assigning it to the dmu_buf_impl_t.
