draw: kill off bogus assertion in tgsi_fetch_gs_outputs

Not sure why it was there but it is definitely not an error if gs outputs are
infs/nans. Besides, the outputs can be ints, in which case any small negative
number asserted.
This fixes piglit's texelFetch gs isamplerXX crashes with softpipe (down from
14 to 2).
