Subject: [PATCH 181/217] cxl/memdev: Fix json for multi-device partitioning
In the case when someone partitions several devices at once, collect all
the affected memdevs into a json array.
With the move to use util_display_json_array() that also requires a set of
flags to be specifiied. Apply the UTIL_JSON_HUMAN flag for all interactive
command result output to bring this command in line with other tools.
