Fix warnings in fwscanf / rewind tests.
This patch fixes "set but not used" warnings in the tests
libio/bug-rewind.c and libio/bug-rewind2.c by checking the return
values from fwscanf and making the tests fail if those values aren't
as expected.
Tested for x86_64.
* libio/bug-rewind.c (do_test): Check fwscanf return values.
* libio/bug-rewind2.c (do_test): Likewise.
