Use guard(mutex) in sev_snp_init_protected_guest_state() and pull in its lock-protected inner helper. Without an unlock trampoline (and even with one), there is no real need for an inner helper. Eliminating the helper also avoids having to fixup the open coded "lockdep" WARN_ON(). Opportunistically drop the error message if KVM can't obtain the pfn for the new target VMSA. The error message provides zero information that can't be gleaned from the fact that the vCPU is stuck.

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.
