Stop kicking vCPUs in kvm_arch_sync_dirty_log() when PML is disabled. Kicking vCPUs when PML is disabled serves no purpose and could negatively impact guest performance. This restores KVM's behavior to prior to 5.12 commita018eba538("KVM: x86: Move MMU's PML logic to common code"), which replaced a static_call_cond(kvm_x86_flush_log_dirty) with unconditional calls to kvm_vcpu_kick().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
