Btrfs: Include map_type in raid_bio
Corrent code use many kinds of "clever" way to determine operation
target's raid type, as:
raid_map != NULL
or
raid_map[MAX_NR] == RAID[56]_Q_STRIPE
To make code easy to maintenance, this patch put raid type into
bbio, and we can always get raid type from bbio with a "stupid"
way.
