Remove the INVVPID capabilities checks from vpid_sync_vcpu_single() and vpid_sync_vcpu_global() now that all callers ensure the INVVPID variant is supported. Note, in some cases the guarantee is provided in concert with hardware_setup(), which enables VPID if and only if at least of invvpid_single() or invvpid_global() is supported. Drop the WARN_ON_ONCE() from vmx_flush_tlb() as vpid_sync_vcpu_single() will trigger a WARN() on INVVPID failure, i.e. if SINGLE_CONTEXT isn't supported.

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.
