btrfs: factor out space reservation code from btrfs_buffered_write()
Inside the main loop of btrfs_buffered_write(), we have a complex data
and metadata space reservation code, which tries to reserve space for
a COW write, if failed then fallback to check if we can do a NOCOW
write.
Factor out that part of code into a dedicated helper, reserve_space(),
to make the main loop a little easier to read.
