Bluetooth: Controller: Fix SCHED_ADVANCED cond, compilation
Bluetooth: Controller: Fix SCHED_ADVANCED cond, compilation

Code under SCHED_ADVANCED macro in ctrl.c is used to
disable advanced radio time space scheduling calculations
used for placing non-overlapping observer and master roles;
to populate connection parameter request/response PDU
fields, and autonomous generation of slave initiated
connection parameter requests.

This macro shall always be enabled for optimal and correct
operation of the controller, It shall only be disabled to
debug failures in other part of the controller, to rule out
this code's influence, if any, on the failure being
debugged.
