[dpdk-stable] [PATCH] examples/vm_power_manager: fix string null termination

[Reshma Pattan]

After the read() the jason_data null termination is missing
for the case "indent < 0", for "indent > 0" and "indent == 0"
cases null termination is already handled.

So add the missing case "indent < 0" to the existing "indent == 0"
case to fix null termination.

Coverity issue: 337680
Fixes: a63504a90f ("examples/power: add JSON string handling")
