qcacmn: Fix kernel 4.15 timer list dependencies

Browse Source 
With the changes made in Ibe0f8adc4df7bb98aceb509d438e241fac507393 and
Ic4cef0d6301230197443d4d5247188f2af643674 there are compilation issues
with converged code.

Resolve the issues by creating ifdefs for the timer_list definitions
according to kernel version.
