Description AubreyLi intel_group 2022-12-06 11:19:14 UTC 
vdcm allocate migration pages at the following flow:

vdcm_vidxd_create()
-> vfio_pci_migration_init()
--> vfio_pci_device->mig_pages = kzalloc()

But migration pages are not free during vdcm removed
idxd_vdcm_remove()

This is certainly a memory leak need to be fixed.
