qemu: Use qemuDomainRequiresMlock() when attaching PCI hostdev
The function is used everywhere else to check whether the locked memory limit should be set / updated, and it should be used here as well. Moreover, qemuDomainGetMlockLimitBytes() expects the hostdev to have already been added to the domain definition, but we only do that at the end of qemuDomainAttachHostPCIDevice(). Work around the issue by adding the hostdev before adjusting the locked memory limit and removing it immediately afterwards.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
