Eliminate more __must_check madness.
The return code from device_for_each_child() depends on the values
which the helper function returns. If the helper function always
returns zero, it's utterly pointless to check the return code from
device_for_each_child().
The only code which knows if the return value should be checked is
the caller itself, so forcing the return code to always be checked
is silly. Hence, remove the __must_check annotation.
