btrfs: fix range_end calculation in extent_write_locked_range
The range_end field in struct writeback_control is inclusive, just like
the end parameter passed to extent_write_locked_range. Not doing this
could cause extra writeout, which is harmless but suboptimal.
Fixes: 771ed689d2cd ("Btrfs: Optimize compressed writeback and reads")
