[PATCH] net/cnxk: fix segmentation fault in telemetry

[Usman Tanveer]

It gives segmentation fault when no parameter is passed for
command '/cnxk/ipsec/info' in usertools/telemetry app as NULL
is being passed as parameter to strtoul(). Now this function
returns -1 before strtoul() if no parameter is passed.
