[BUG] calling btrfs.resize from module.run fails

Description
When calling the module btrfs.resize from a module.runstanza it fails with NameError: name '__salt__' is not defined
Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

Please be as specific as possible and give set-up details.

• on-prem machine
• VM (Virtualbox, KVM, etc. please specify)
• [X ] EC2 instance on ARM
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit
• jails if it is FreeBSD
• classic packaging
• onedir packaging
• used bootstrap to install

Steps to Reproduce the behavior

Have a sls file with this content:

resize /data filesystem:
  module.run:
    - btrfs.resize:
      - mountpoint: /data
      - size: max

When /data is a mounted btrfs filesystem.

I'm getting

          ID: resize /data filesystem
    Function: module.run
      Result: False

Expected behavior
it should work, it seems that if I specify a size and not max it's not erroring.

Start with salt/modules/btrfs.py at resize and salt/utils/fsutils.py at _is_device, then reproduce the provided module.run SLS with a mounted Btrfs filesystem and size: max. The fix is done when this invocation completes without the reported salt NameError and behaves like the non-max resize case.
