We do not need a case switch to check cap_type_id in intel_vgpu_ioctl for various reasons (it's impossible to hit the default case in the current code, there's only one valid case to check, the error handling code overlaps in both cases, etc.). Simplify the case switch into a single if statement. This has the additional effect of simplifying the error handling code. Note that it is still currently impossible for 'if (cap_type_id == VFIO_REGION_INFO_CAP_SPARSE_MMAP)' to fail, but we should still guard against the possibility of this changing in the future.

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.
