[PATCH master] of: base: Fix of_get_stdoutpath() when property does not contain a colon

[Ahmad Fatoum]

Initial state of patch accounted for lack of colon by skipping xstrdup
in that case. Too much time went by that I forgot before upstreaming,
 why I did it that way and thus value ended up being dropped...
 Fix this to restore console for devices which lack : in their
 stdout-path.

Fixes: 90f70dbe2958 ("of: split part of of_get_stdoutpath into of_find_node_by_chosen")
