[PATCH 5.7 107/120] selftest: txtimestamp: fix net ns entry logic

[Greg Kroah-Hartman]

From: Paolo Pisati <paolo.pisati@xxxxxxxxxxxxx>

[ Upstream commit b346c0c85892cb8c53e8715734f71ba5bbec3387 ]

According to 'man 8 ip-netns', if `ip netns identify` returns an empty string,
there's no net namespace associated with current PID: fix the net ns entrance
logic.
