Btrfs: fix bitmap size tracking
When we first go to add free space, we allocate a new info and set the offset
and bytes to the space we are adding. This is fine, except we actually set the
size of a bitmap as we set the bits in it, so if we add space to a bitmap, we'd
end up counting the same space twice. This isn't a huge deal, it just makes
the allocator behave weirdly since it will think that a bitmap entry has more
space than it ends up actually having. I used a BUG_ON() to catch when this
problem happened, and with this patch I no longer get the BUG_ON().
