btrfs: use a constant for the number of metadata units needed for an unlink
Instead of hard coding the number of metadata units for an unlink operation in a couple places, define a macro and use it instead. This eliminates the problem of one place getting out of sync with the other, such as recently fixed by the previous patch in the series ("btrfs: fix calculation of the global block reserve's size").
