wined3d: Initialize maxAttribs in case it isn't changed by glGetIntegerv.

[Philip Nilsson]

My OpenGL implementation (NVIDIA's binary driver, version 169.12)
returns GL_NO_ERROR in this function, but doesn't change the passed
value.  Uninitialized maxAttribs might be about 1500000 and thus
generate a couple hundred megabytes of GL_CHECK_CALL errors.

16 is what is set if glGetIntegerv returns some error, and is also the
minimum value required by an implementation.
