nrf52_bsim: Fix possible NULL pointer dereference

Browse source 
Fixed a very unlikely NULL pointer dereference, which could occur
in an error condition, triggered if the test/fake HW timer model
was enabled but there was no registered handler for that timer tick.

The de-reference was in the error message printout.

Fixes #10778
