[PATCH 2/2] Documentation: PCI: extend subheading underline for "lspci output" section

[Bagas Sanjaya]

The underline syntax for "lspci output..." section is off-by-one less
than the section heading's length, hence triggers the warning:

Documentation/PCI/endpoint/pci-vntb-howto.rst:131: WARNING: Title underline too short.

Extend the underline by one to match the heading length.
