vc4: Avoid false scheduling dependencies for LOAD_IMMs.

Noticed in shaders with branching, where we ended up scheduling delay
slots near the start of a block for the uniforms reset setup.

total instructions in shared programs: 93970 -> 93951 (-0.02%)
instructions in affected programs:     3117 -> 3098 (-0.61%)

3DMMES performance +0.423087% +/- 0.133521% (n=9,10)
