[Mesa-dev] [PATCH] freedreno/ir3: fix immediate usage in tgsi tex fe

[Ilia Mirkin]

get_immediate will return a const reference, the requested immediate
isn't necessarily in the x slot. Make sure to use the swizzle.

I know you're behind the "death to TGSI frontend" banner, but while it's
around, should probably fix it up...
