glsl: Fix copy-paste error in constant_expression_value(ir_binop_nequal)

The implementation of ir_binop_nequal in constant_expression_value()
appears to have been copy-and-pasted from the implementation of
ir_binop_equal, but with all instances of '==' changed to '!='.  This
is correct except for one minor flaw: one of those '==' operators was
in an assertion checking that the types of the two arguments were
equal.  That one needs to stay an '=='.

Fixes piglit tests {fs,vs}-inline-notequal.
