Andrea Bolognani c2e60ad0e5 qemu: Forbid <memoryBacking><locked> without <memtune><hard_limit>
In order for memory locking to work, the hard limit on memory
locking (and usage) has to be set appropriately by the user.

The documentation mentions the requirement already: with this
patch, it's going to be enforced by runtime checks as well,
by forbidding a non-compliant guest from being defined as well
as edited and started.
