Remove unused variable gma_bottom in scan_workload() and scan_wa_ctx(). commitbe1da7070a("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.
