Subject: [PATCH] drmgr: load rpadlpar_io on -C as well

References: bnc#1064039, bsc#1070113

Users do drmgr -C to verify their system.

However, -C does not select any hotplug type, and the rpadlpar_io kernel
module is loaded only when hotplug type pci, phb or slot is selected.

Make display_capabilities global and check it in check_kmods()
