Revert "globally limit the maximum number of CPUs"

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2094270 Upstream Status: RHEL-only Tested: with upstream kernel

Downstream QEMU carries a patch that sets the hard limit of possible vCPUs to the value that the KVM code of the kernel recommends as soft limit. Upstream KVM code has been changed recently to not use an arbitrary soft limit anymore, but to cap the value on the amount of available physical CPUs of the host. This defeats the purpose of the downstream change in QEMU completely. Drop the downstream-only patch to allow CPU overcommit.

This reverts commit 6669f6fa.
