Fixes #669.
The last step of the
volk_32f_x2_dot_prod_16i
kernel is a conversion from float to int16. Floating point error in the dot product calculation will inevitably lead to an output difference of 1 when the answer is close to an integer threshold. As with #647, the only reasonable fix in the current test framework is to increase the tolerance to 1.
