btrfs: move end_io_func argument to btrfs_bio_ctrl structure

Browse source

For function submit_extent_page() and alloc_new_bio(), we have an
argument @end_io_func to indicate the end io function.

But that function never change inside any call site of them, thus no
need to pass the pointer around everywhere.

There is a better match for the lifespan of all the call sites, as we
have btrfs_bio_ctrl structure, thus we can put the endio function
pointer there, and grab the pointer every time we allocate a new bio.

Also add extra ASSERT()s to make sure every call site of
submit_extent_page() and alloc_new_bio() has properly set the pointer
inside btrfs_bio_ctrl.

This removes one argument from the already long argument list of
submit_extent_page().
