iwlwifi: iwl-dbg: Use del_timer_sync() before freeing
In Chrome OS, a large number of crashes is observed due to corrupted timer
lists. Steven Rostedt pointed out that this usually happens when a timer
is freed while still active, and that the problem is often triggered
by code calling del_timer() instead of del_timer_sync() just before
freeing.
Steven also identified the iwlwifi driver as one of the possible culprits
since it does exactly that.
