Remove the VM_KMPAGESFREE sysctl. After the pmemrange

changes it was returing a constant 0, changing to cope
with those changes makes less sense then just removing
as it provides the user with no usefull information.

sthen@ grepped the port's tree for me and found not hits,
thanks!

OK deraadt@, matthew@
