In the future we're going to have multiple csum and extent root trees,
so init the roots block_rsv at setup_root time based on their root key
objectid.

We used to need the root for btrfs_reserve_metadata_bytes to check the
orphan cleanup state, but we no longer need that, we simply need the
fs_info. Change btrfs_reserve_metadata_bytes() to use the fs_info, and
change both btrfs_block_rsv_refill() and btrfs_block_rsv_add() to do the
same as they simply call btrfs_reserve_metadata_bytes() and then
manipulate the block_rsv that is being used.

Currently the non-prefixed version is a simple wrapper used to hide
the 4th argument of the prefixed version. This doesn't bring much value
in practice and only makes the code harder to follow by adding another
level of indirection. Rectify this by removing the __ prefix and
have only one public function to release bytes from a block reservation.
No semantic changes.

The delalloc reserve stuff calls this directly because it cares about
the qgroup accounting stuff, so export it so we can move it around. Fix
btrfs_block_rsv_release() to just be a static inline since it just calls
__btrfs_block_rsv_release() with NULL for the qgroup stuff.

This is used in a few places, we need to make sure it's exported so we
can move it around.

Prep work for separating out all of the block_rsv related code into its
own file.
