samples: bluetooth: llpm: Enable sample to run without security protocol

rob-robinson-14 · rob-robinson-14 · commit 9204e64bc339 · 2025-07-11T08:50:12.000+01:00
On devices where security manager has not yet been implemented,
it is useful to still be able to test bluetooth functionality through
llpm sample.
