kvm_vm_elf_load() and elfhdr_get() open one file each, but they never close the opened file descriptor. If a test repeatedly creates and destroys a VM with __vm_create(), which (directly or indirectly) calls those two functions, the test might end up getting a open failure with EMFILE. Fix those two functions to close the file descriptor.

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.
