[Mesa-dev] [PATCH 3/6] panfrost: Control texop value earlier

[Boris Brezillon]

Right now the failure happens when building the midgard texture
instruction. Since we're about to add support for texop_txs (texture
size) which is does not involve the creation of a texture instruction,
let's add a instr->op check at the beginning of the emit_tex() function
so we can easily branch to a different path when needed.
