[PATCH 7/7] multipath: print sysfs state in fast list mode

["Benjamin Marzinski" <bmarzins@redhat.com>]

commit b123e711ea2a4b471a98ff5e26815df3773636b5 "libmultipath: cleanup
orphan device states" stopped multipathd from showing old state for
orphan paths by checking if pp->mpp was set, and only printing the state
if it was.   Unfortunately, when "multipath -l" is run, pp->mpp isn't
set. While the checker state isn't checked and shouldn't be printed with
"-l", the sysfs state can be, and was before b123e711. This patch sets
pp->mpp in fast list mode, so that the sysfs state gets printed.
