This split write back buffer handling into 3 functions, wb_fini for cleanup, wb_enable/wb_disable for enabling/disabling write back used for suspend/resume. This should fix potential issue of letting the write back active before suspending. We need to allocate memory in wb_enable because we can only allocate once GART is running.
