[PATCH] memtest: fix list iteration in region setup

When memory regions start at 0, the current mem_test_request_regions function
wrongly assumes that struct resource *r points at the correct region. It points
to the first region however (which starts at 0).
The comment states, that the code starts from the second entry.
In include/linux/list.h the macro documentation however says:
list_for_each_entry_from - iterate over list of given type from the current point
The correct list iteration macro to use here is list_for_each_entry_continue,
where the documentation says:
Continue to iterate over list of given type, continuing after
the current position.
