btrfs: use integrated bitmaps for scrub_parity::dbitmap and ebitmap
Previously we use "unsigned long *" for those two bitmaps.
But since we only support fixed stripe length (64KiB, already checked in
tree-checker), "unsigned long *" is really a waste of memory, while we
can just use "unsigned long".
This saves us 8 bytes in total for scrub_parity.
To be extra safe, add an ASSERT() making sure calclulated @nsectors is
always smaller than BITS_PER_LONG.
