API of_parse_phandle_with_args_map() will use wrong input for nexus node
Nexus_2 as shown below:

    Node_1		Nexus_1                              Nexus_2
&Nexus_1,arg_1 -> arg_1,&Nexus_2,arg_2' -> &Nexus_2,arg_2 -> arg_2,...
		  map-pass-thru=<...>

Nexus_1's output arg_2 should be used as input of Nexus_2, but the API
wrongly uses arg_2' instead which != arg_2 due to Nexus_1's map-pass-thru.

Fix by always making @match_array point to @initial_match_array into
which to store nexus output.
