    sys/arm64: fix return values of freebsd32_{set,swap}context()
    
    This patch aligns the return values of freebsd32_{set,swap}context()
    with their counterparts on amd64 and powerpc64, fixing the setcontext()
    and swapcontext() calls in armv7 applications running on aarch64.
    
    In particular, this fixes random crashes in armv7 Ruby applications
    running on aarch64 hosts.
    
    Tested by:      fuz
    MFC after:      1 week
