btrfs: don't take a bio_counter reference for cloned bios
Stop grabbing an extra bio_counter reference for each clone bio in a
mirrored write and instead just release the one original reference in
btrfs_end_bioc once all the bios for a single btrfs_bio have completed
instead of at the end of btrfs_submit_bio once all bios have been
submitted.
This means the reference is now carried by the "upper" btrfs_bio only
instead of each lower bio.
Also remove the now unused btrfs_bio_counter_inc_noblocked helper.
