Patch arraysize receiving argument sysctl

both binary package and ports compiled version fail

$ wmmemload
Abort

leaving line in /var/log/messages:

Jun 14 15:35:33 azd wmmemload[55487]: stack overflow detected; terminated
Jun 14 15:35:33 azd kernel: pid 55487 (wmmemload), jid 0, uid 1001: exited on
signal 6

Problem seems to be fixed size of mib array in src/mem_freebsd.c
For descendants of "vm.swap_info" array size should be 3
