Use the recently added tracepoint for logging nested VM-Enter failures instead of spamming the kernel log when hardware detects a consistency check failure. Take the opportunity to print the name of the error code instead of dumping the raw hex number, but limit the symbol table to error codes that can reasonably be encountered by KVM. Add an equivalent tracepoint in nested_vmx_check_vmentry_hw(), e.g. so that tracing of "invalid control field" errors isn't suppressed when nested early checks are enabled.

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.
