[SRU][F:linux-bluefield][PATCH 32/32] net/tls: Except bond interface from some TLS checks

[Daniel Jurgens]

From: Tariq Toukan <tariqt at nvidia.com>

BugLink: https://bugs.launchpad.net/bugs/1926994

In the tls_dev_event handler, ignore tlsdev_ops requirement for bond
interfaces, they do not exist as the interaction is done directly with
the lower device.

Also, make the validate function pass when it's called with the upper
bond interface.
