anv: Check for VK_WHOLE_SIZE in anv_CmdFillBuffer

From the Vulkan spec:

   Size is the number of bytes to fill, and must be either a multiple of 4,
   or VK_WHOLE_SIZE to fill the range from offset to the end of the buffer.
   If VK_WHOLE_SIZE is used and the remaining size of the buffer is not a
   multiple of 4, then the nearest smaller multiple is used.
