Remove unused variable gma_bottom in scan_workload() and scan_wa_ctx().
commit be1da7070aea ("drm/i915/gvt: vGPU command scanner") introduces
gma_bottom in several functions to calculate the size of the command
buffer. However, some of them are set but actually unused.
When compiling the code with ccflags -Wunused-but-set-variable, gcc
throws warnings.
Remove unused variables to avoid the gcc warnings. Tested via compiling
the code with ccflags -Wunused-but-set-variable.
