Refactor s390_reset_acc so that it can be reused in upcoming patches. We don't want to hold all the locks used in a walk_page_range for too long, and the destroy page UVC does take some time to complete. Therefore we quickly gather the pages to destroy, and then destroy them without holding all the locks. The new refactored function optionally allows to return early without completing if a fatal signal is pending (and return and appropriate error code). Two wrappers are provided to call the new function.
