[PATCH v1 2/2] tools: PCI: Fix a typo in usage messages

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

When the commit fbca0b284bd0 ("tools: PCI: Add 'h' in optstring of getopt()")
introduced a fix to support -h command line option, it, at the same time,
brought a regression to the code which produces a compile-time warning:

pcitest.c:203:4: warning: too many arguments for format [-Wformat-extra-args]
    "usage: %s [options]\n"
    ^~~~~~~~~~~~~~~~~~~~~~~

Remove trailing comma to make it correct.
