Ashijeet Acharya 7562f90707 migrate: Introduce a 'dc->vmsd' check to avoid segfault for --only-migratable ... Commit a3a3d8c7 introduced a segfault bug while checking for 'dc->vmsd->unmigratable' which caused QEMU to crash when trying to add devices which do no set their 'dc->vmsd' yet while initialization. Place a 'dc->vmsd' check prior to it so that we do not segfault for such devices. NOTE: This doesn't compromise the functioning of --only-migratable option as all the unmigratable devices do set their 'dc->vmsd'. Introduce a new function check_migratable() and move the only_migratable check inside it, also use stubs to avoid user-mode qemu build failures.
