virtio_pci: fix the common cfg map size
The function vp_modern_map_capability() takes the size parameter, which corresponds to the size of virtio_pci_common_cfg. As a result, this indicates the size of memory area to map. Now the size is the size of virtio_pci_common_cfg, but some feature(such as the _F_RING_RESET) needs the virtio_pci_modern_common_cfg, so this commit changes the size to the size of virtio_pci_modern_common_cfg.

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.
