    aarch64: Fix test_dfp_17.c for big-endian [PR 107604]
    
    gcc.target/aarch64/aapcs64/test_dfp_17.c has been failing on
    big-endian, because the _Decimal32 on-stack argument is not padded in
    the same direction depending on endianness.
    
    This patch fixes the testcase so that it expects the argument in the
    right stack location, similarly to what other tests do in the same
    directory.
