Don't zap valid mirror roots in kvm_tdp_mmu_zap_all(), which in effect is only direct roots (invalid and valid). For TDX, kvm_tdp_mmu_zap_all() is only called during MMU notifier release. Since, mirrored EPT comes from guest mem, it will never be mapped to userspace, and won't apply. But in addition to be unnecessary, mirrored EPT is cleaned up in a special way during VM destruction. Pass the KVM_INVALID_ROOTS bit into __for_each_tdp_mmu_root_yield_safe() as well, to clean up invalid direct roots, as is the current behavior. While at it, remove an obsolete reference to work item-based zapping.

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 reStructuredText 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.
