[PATCH] powerpc/papr_scm: Fix buffer overflow issue with CONFIG_FORTIFY_SOURCE

With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform dynamic checks for string size which can panic the kernel, like incase of overflow detection. In papr_scm, papr_scm_pmu_check_events function uses stat->stat_id with string operations, to populate the nvdimm_events_map array.
