mesa: fix the low limit of width and height for glRenderbufferStorage

Browse Source 
glRenderbufferStorage man page says:

  GL_INVALID_VALUE is generated if either of width or height is negative,
  or greater than the value of GL_MAX_RENDERBUFFER_SIZE.

NOTE: this is a candidate for the 7.11 branch
