radv: trim buffer load result (fixes dota2) 

Running dota2 since the below commit crashes with an llvm assert.

Trim the vector like the other user. This possible could also be
avoided by not padding inside the load vec3->vec4.

Fixes: 41c36c4549 (amd/common: use ac_build_buffer_load() for emitting UBO loads)
