btrfs: fix and document the zoned device choice in alloc_new_bio
Zone Append bios only need a valid block device in struct bio, but
not the device in the btrfs_bio. Use the information from
btrfs_zoned_get_device to set up bi_bdev and fix zoned writes on
multi-device file system with non-homogeneous capabilities and remove
the pointless btrfs_bio.device assignment.
Add big fat comments explaining what is going on here.
