Shuicheng Lin 9d80698bcd drm/xe: Add config control for svm flush work 
Without CONFIG_DRM_XE_GPUSVM set, GPU SVM is not initialized thus below
warning pops. Refine the flush work code to be controlled by the config
to avoid below warning:

v2 (Matt):
    refine commit message to have more details
    add Fixes tag
    move the code to xe_svm.h which already have the config
    remove a blank line per codestyle suggestion
