initcall: Adjust the failure message and return value

Move the failure message outside the loop, so it is easier to follow the
code. Avoid swallowing the error code - just pass it along.

Drop the initcall-list address from the output. This is confusing since
we show two addresses. Really it is only the function address which is
useful, since it can be looked up in the map, e.g. with:

   grep -A1 -B1 serial_init u-boot.map
