Fix below warnings reported by coccicheck:
drivers/vdpa/vdpa_sim/vdpa_sim.c:104:1-10: WARNING: Assignment of 0/1 to bool variable
drivers/vdpa/vdpa_sim/vdpa_sim.c:164:7-11: WARNING: Unsigned expression compared with zero: read <= 0
drivers/vdpa/vdpa_sim/vdpa_sim.c:169:7-12: WARNING: Unsigned expression compared with zero: write <= 0
1. The 'ready' variable in vdpasim_virtqueue struct is bool type.
It is better to initialize vq->ready to false
2. Modify 'read' and 'write' variables type from size_t to ssize_t.
And preserve the reverse christmas tree ordering of local variables.

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.
