[PATCH v2 10/10] powerpc/hv-24x7: Break up single_24x7_request

Break up the function single_24x7_request() into smaller functions. This would later enable us to "prepare" a multi-event request buffer and then submit a single hcall for several events. Changelog[v2]: [Michael Ellerman] Rename start_24x7_get_data() to init_24x7_request()
