Subject: [PATCH 6/8] udiskslinuxmdraidobject: Optimize unused data out from
 the g_io_channel_read_to_end() call

Looking into glib sources the g_io_channel_read_to_end() function
can handle NULL output pointers just fine and since the data is thrown
right away it's pointless to have them assigned.
