mesa/clear: remove dead code handling ClearBufferiv(GL_DEPTH) 

There's a hunk above which sets INVALID_ENUM for GL_DEPTH
unconditionally.

* "The result of ClearBuffer is undefined if no conversion between
* the type of the specified value and the type of the buffer being
* cleared is defined (for example, if ClearBufferiv is called for a
* fixed- or floating-point buffer, or if ClearBufferfv is called
* for a signed or unsigned integer buffer). This is not an error."
*
* In this case we take "undefined" and "not an error" to mean "ignore."
* Note that we still need to generate an error for the invalid
* drawbuffer case (see the GL_STENCIL case above).
