Btrfs: try committing transaction before returning ENOSPC
This fixes a problem where we could return -ENOSPC when we may actually have
plenty of space, the space is just pinned. Instead of returning -ENOSPC
immediately, commit the transaction first and then try and do the allocation
again.
This patch also does chunk allocation for metadata if we pass the 80%
threshold for metadata space. This will help with stack usage since the chunk
allocation will happen early on, instead of when the allocation is happening.
