This name doesn't really fit with how the space reservation stuff works
now, rename it to btrfs_space_info_free_bytes_may_use so it's clear what
the function is doing.

Now that we do not do partial filling of tickets simply remove
orig_bytes, it is no longer needed.

Now that btrfs_space_info_add_old_bytes simply checks if we can make the
reservation and updates bytes_may_use, there's no reason to have both
helpers in place.
Factor out the ticket wakeup logic into it's own helper, make
btrfs_space_info_add_old_bytes() update bytes_may_use and then call the
wakeup helper, and replace all calls to btrfs_space_info_add_new_bytes()
with the wakeup helper.

We duplicate this tracepoint everywhere we call these helpers, so update
the helper to have the tracepoint as well.

to use it. This is prep work to move reserve_metadata_bytes.
