Subject: NTB: ntb_test: fix bug printing ntb_perf results

From: Logan Gunthorpe <[email protected]>

commit 07b0b22b3e58824f70b9188d085d400069ca3240 upstream.

The code mistakenly prints the local perf results for the remote test so the script reports identical results for both directions. Fix this by ensuring we print the remote result.

Fixes a9c59ef77458 ("ntb_test: Add a selftest script for the NTB subsystem")
