x86/resctrl: Initialize on-stack struct rmid_read instances
New semantics rely on some struct rmid_read members having NULL values to
distinguish between the SNC and non-SNC scenarios. resctrl can thus no longer
rely on this struct not being initialized properly.
Initialize all on-stack declarations of struct rmid_read:
rdtgroup_mondata_show()
mbm_update()
mkdir_mondata_subdir()
to ensure that garbage values from the stack are not passed down to other
functions.
