Commit f06b222 ("fixes for QEMU 9.0") included a revert for the QEMU
commit 2ce6cff94d ("virtio-pci: fix use of a released vector"). That
commit caused some regressions which sounded just as bad as the fix.
Those regressions have now been addressed upstream, so pick up the fix
and drop the revert. Dropping the revert fixes the original issue that
commit 2ce6cff94d ("virtio-pci: fix use of a released vector")
addressed.

We made a copy above because the fp exception flags
|
|
are not propagated back to the FPST register, but
|
|
then failed to use the copy.
