Bluetooth: controller: llcp: serialize phy update notifications

Browse source 
The PHY update procedure may trigger a DLE update in certain
situations
When a limited number of rx buffers is available there may not be
enough for doing the phy update and dle update notifications
at once.

Fixes #41788
