iris, crocus: Disable new IO slot validation for FB fetch load_output

Browse Source 
This is a framebuffer fetch for blend equation advanced lowering.  We're
using a binding table index as the offset, which is not a slot.

Also, validate the shader after setup_binding_table so that we catch
errors here at the right place, rather than deeper in the compiler.
