Remove KVM's unnecessary zeroing of memory when allocating the pages array in sev_pin_memory() via __vmalloc(), as the array is only used to hold kernel pointers. The kmalloc() path for "small" regions doesn't zero the array, and if KVM leaks state and/or accesses uninitialized data, then the kernel has bigger problems.

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.
