Use BTRFS_MAX_METADATA_BLOCKSIZE and SZ_4K (minimal sectorsize) to calculate this value. And remove one stale comment on the value, in fact with recent subpage support, BTRFS_MAX_METADATA_BLOCKSIZE * PAGE_SIZE is already beyond BTRFS_STRIPE_LEN, just we don't use the full page. Also since we're here, update the BUG_ON() related to SCRUB_MAX_PAGES_PER_BLOCK to ASSERT(). As those ASSERT() are really only for developers to catch early obvious bugs, not to let end users suffer.
