docs: admin-guide: Fix default value of max_map_count in sysctl/vm.rst
Since the default value of sysctl_max_map_count is defined as
DEFAULT_MAX_MAP_COUNT from mm/util.c
int sysctl_max_map_count __read_mostly = DEFAULT_MAX_MAP_COUNT;
DEFAULT_MAX_MAP_COUNT is defined as 65530 (65535-5) in include/linux/mm.h
#define MAPCOUNT_ELF_CORE_MARGIN (5)
#define DEFAULT_MAX_MAP_COUNT (USHRT_MAX - MAPCOUNT_ELF_CORE_MARGIN)
