Christian Borntraeger e8d12a55f6 s390x/pv: Retry ioctls on -EINTR
PV_ENABLE (and maybe others) might return -EINTR when a signal is
pending. See the Linux kernel patch "s390/gmap: return proper error code
on ksm unsharing" for details. Let us retry the ioctl in that case.

Fixes: c3347ed0d2ee ("s390x: protvirt: Support unpack facility")
