fpu/softfloat.c: Return correctly signed values from uint64_to_float32

The uint64_to_float32() conversion function was incorrectly always returning numbers with the sign bit set (ie negative numbers). Correct this so we return positive numbers instead. Signed-off-by: Peter Maydell <[email protected]> Signed-off-by: Aurelien Jarno <[email protected]>
