s390/hypfs: include z/VM guests with access control group set
Currently if z/VM guest is allowed to retrieve hypervisor performance data globally for all guests (privilege class B) the query is formed in a way to include all guests but the group name is left empty. This leads to that z/VM guests which have access control group set not being included in the results (even local vm). Change the query group identifier from empty to "any" to retrieve information about all guests from any groups (or without a group set).
