Remove fs_info->max_zone_append_size, it doesn't serve any purpose.

Changes to v1:
- also remove the local max_zone_append_size variable in
  btrfs_check_zoned_mode() (Anand)

And what about btrfs_zoned_device_info::max_zone_append_size, should it
also be removed? In case you don't have plans with it I'll remove it, no
need to resend, it's just a few more lines but want to know if it's
accidental or intentional.

I /think/ this one can stay until we work on multi-device/RAID support.

We are nowhere near close to this for now, so I am all for removing it.

OK then let's get rid of it all. The block layer knows the limits when
we're constructing a bio.
