Btrfs: make btrfs_map_block() return entire free extent for each device of RAID0/1/10/DUP

btrfs_map_block() will only return a single stripe length, but we want the
full extent be mapped to each disk when we are trimming the extent,
so we add length to btrfs_bio_stripe and fill it if we are mapping for REQ_DISCARD.
