virgl: don't move input gl_SampleMaskIn to a temp
The input is an array so moving it to a single temporary value doesn't
seem to make much sense. I also don't see any piglit regressions when
not moving the value to a temporary.
Fixes: bc912bace1
virgl: Add workarounds for virglrenderer input/sv signedness bugs.
v2: remove unused enum for SAMPLEMASK (Emma)
