btrfs: rename bitmap_set_bits() -> btrfs_bitmap_set_bits()

bitmap_set_bits() does not start with the FS' prefix and may collide
with a new generic helper one day. It operates with the FS-specific
types, so there's no change those two could do the same thing.
Just add the prefix to exclude such possible conflict.
