nir: Silence unused parameter warnings in nir_constant_expression.c

nir/nir_constant_expressions.c:290:25: warning: unused parameter 'num_components' [-Wunused-parameter]
 evaluate_ball3(unsigned num_components, nir_const_value *_src)
                         ^
nir/nir_constant_expressions.c: In function 'evaluate_fddx':
nir/nir_constant_expressions.c:1282:57: warning: unused parameter '_src' [-Wunused-parameter]
 evaluate_fddx(unsigned num_components, nir_const_value *_src)
                                                         ^

v2: Unconditionally mark the parameters as MAYBE_UNUSED instead of
conditionally adding (void) casts to keep the generator simple.
Suggested by Jason.

Number of total warnings in my build reduced from 1575 to 1485
(reduction of 89).
