[Mesa-stable] [Mesa-dev] [PATCH] gallium/util: initialize pipe_framebuffer_state to zeros

[Brian Paul]

According to the p_state.h file,

    unsigned samples; /**< Number of samples in a no-attachment 
framebuffer */
    unsigned layers;  /**< Number of layers  in a no-attachment 
framebuffer */

so since the fb has attachments here, I think those fields are unused.

Cc'ing Edward since he added the fields.
