tests: Bluetooth: df: fix compilation error in per adv chain tests

There was a change in parameters list of function ull_adv_sync_pdu_-
alloc. There was a call in commmon.c file in connectionless_cte_chains
unit tests with use of former parameters list. That caused a compilation
error.

The commit fixes the compilation issue.
