[PATCH] adapter: Fix storing the IRK on first boot.

[Kai Ruhnau <kai.ruhnau@target-sg.com>]

From: Kai Ruhnau <kai.ruhnau@target-sg.com>

generate_and_write_irk doesn't create the adapter directory and
doesn't check for errors when persisting the IRK which currently
fails on first boot. This fixes both.
