s390/vfio-ap: Fix control domain removal in vfio_ap_mdev_cfg_remove

In the Linux kernel, the following vulnerability has been resolved:

s390/vfio-ap: Fix control domain removal in vfio_ap_mdev_cfg_remove

The vfio_ap_config_remove function uses the bitmap_andnot function to clear
bits from the matrix_mdev->matrix.adm bitmap (specifies the control domains
assigned to the mdev). This prevents the explicitly unplugged control
domains from being removed the KVM guest. The bitmap_and function is used
instead.
