[PATCH] app/testpmd: fix set Tx offload command

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

In command to set Tx offload:
"port config <port_id> tx_offload <offload> on|off",

there is a defect in "on|off" comparison, so command does opposite of
what is intended. Fixed comparison.

Fixes: 6280fe565b44 ("app/testpmd: allow offload config for all ports")
