process_eventdev_xstats() function was iterating over
eventdev_var[] structure even if there is no eventdev present.
Revised the code to check to iterate and only look for the number
of eventdevs present in the system. Also, shortened function name to
eventdev_xstats().

Coverity issue: 395458
Fixes: 674bb3906931 ("app/procinfo: display eventdev xstats")
