remove incorrect checker for acl command

in case of empty mask (---), there is possibility of block effective permissions for adm group
so , there are 2 ways:
1) change unless checker:

 - unless: "getfacl /var/log/|grep default:group:adm && getfacl /var/log/|grep mask::r"
2) remove this checker

IMO:
1) bad code-style
2) better solution for me, because imo, this checker is redundant, because:
  - setfacl command doesnot return non-zero exit code due reapplying
  - setfacl command doesnot need much time or cpu/memory resources, so wrapping is redundant
