[PATCH net] selftests: drv-net: psp: skip unsupported versions in netkit data test

[Alexey Skidanov via B4 Relay <devnull+alexeys.xsightlabs.com@kernel.org>]

From: Alexey Skidanov <alexeys@xsightlabs.com>

data_basic_send_netkit_psp_assoc() runs for PSP versions 0-3. The
non-netkit data path already skips versions the device does not
advertise in psp-versions-cap. The netkit path does not, so those
cases fail instead of skipping.

Version 0 stays mandatory. Skip an unadvertised version before opening
the PSP connection.

Fixes: 43cf629700fa ("selftests/net: psp: add dev-assoc data path test")
