qcacmn: Add conditional macro for tracing threads

Browse Source 
Kernel 5.2 has removed the stack_trace struct and replaced
print_stack_trace() and save_stack_trace_tsk() with stack_trace_print()
and stack_trace_save_tsk() respectively. Add a conditional preprocessor
directive to use save_trace_print() and stack_trace_save_tsk() and call
them with the appropriate updated parameters.
