Paolo,
two fixes for s390.

Turning gisa off was making us write an uninitialized value into the
SIE control block due to the V!=R changes.

Errors when (un)sharing SE memory which were previously unchecked are
now resulting in panics since there's nothing that the guest can do to
fix the situation.

Please pull.

The following changes since commit de9c2c66ad8e787abec7c9d7eff4f8c3cdd28aed:

  Linux 6.11-rc2 (2024-08-04 13:50:53 -0700)
