[dpdk-stable] [PATCH v2 2/7] app/procinfo: fix negative check on unsigned variable

[Ferruh Yigit <ferruh.yigit@intel.com>]

'parse_xstats_ids()' return 'int'. The return value is assigned to
'nb_xstats_ids' unsigned value, later negative check on this variable is
wrong.

Adding interim 'int' variable for negative check.

Fixes: 7ac16a3660c0 ("app/proc-info: support xstats by ID and by name")
