mm/vmstat.c: fix outdated vmstat_text
commit 28e2c4bb99aa40f9d5f07ac130cbc4da0ea93079 upstream. 7a9cdebdcc17 ("mm: get rid of vmacache_flush_all() entirely") removed the VMACACHE_FULL_FLUSHES statistics, but didn't remove the corresponding entry in vmstat_text. This causes an out-of-bounds access in vmstat_show(). Luckily this only affects kernels with CONFIG_DEBUG_VM_VMACACHE=y, which is probably very rare.
