Naohiro Aota 08e11a3db0 btrfs: zoned: load zone's allocation offset 
A zoned filesystem must allocate blocks at the zones' write pointer. The
device's write pointer position can be mapped to a logical address within
a block group. To facilitate this, add an "alloc_offset" to the
block-group to track the logical addresses of the write pointer.

This logical address is populated in btrfs_load_block_group_zone_info()
from the write pointers of corresponding zones.

For now, zoned filesystems the single profile. Supporting non-single
profile with zone append writing is not trivial. For example, in the DUP
profile, we send a zone append writing IO to two zones on a device. The
device reply with written LBAs for the IOs. If the offsets of the
returned addresses from the beginning of the zone are different, then it
results in different logical addresses.

We need fine-grained logical to physical mapping to support such separated
physical address issue. Since it should require additional metadata type,
disable non-single profiles for now.

This commit supports the case all the zones in a block group are
sequential. The next patch will handle the case having a conventional
zone.
