Fix warnings in fwscanf / rewind tests.

Browse Source 
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.
