btrfs: fix balance range usage filters in 4.4-rc
There's a regression in 4.4-rc since commit bc3094673f22 (btrfs: extend balance filter usage to take minimum and maximum) in that existing (non-ranged) balance with -dusage=x no longer works; all chunks are skipped. After staring at the code for a while and wondering why a non-ranged balance would even need min and max thresholds (..which then were not set correctly, leading to the bug) I realized that the only problem was the fact that the filter functions were named wrong, thanks to patching copypasta. Simply renaming both functions lets the existing btrfs-progs call balance with -dusage=x and now the non-ranged filter function is invoked, properly using only a single chunk limit.
