    Fix drop_move_claim() on revert resize

    On revert_resize(), the migration context was dropped hence setting it
    to None. The problem is that the migration context is needed when
    executing finish_revert_resize() so that the neutron port can be updated
    with the right binding profile.

    This patch moves the instance.drop_migration_context() call out from the
    resource tracker so that the migration context can be dropped at the
    appropriate times: after RT.drop_move_claim() is called in the compute
    manager's confirm_resize() call and after the virt driver's
    finish_revert_resize() in the compute manager's finish_revert_resize()
    call.
