swscale/input: clip rgbf32 values before lrintf

if the float pixel * 65535.0f > 2147483647.0f
lrintf may overfow and return negative values, depending on implementation.
nan and +/-inf values may also be implementation defined

clip the value first so lrintf always works.

values <     0.0f, -inf, nan = 0.0f
values > 65535.0f, +inf      = 65535.0f
