btrfs: add correction to handle -1 edge case in async discard From Dave's testing, it's possible to drive a file system to have -1 discardable_extents and a corresponding negative discardable_bytes. As btrfs_discard_calc_delay() is the only user of discardable_extents, we can correct here for any negative discardable_extents/discardable_bytes.
