Please consider the following patch that fixes a kernel panic on 
removing and inserting the ipmi_ssif module in a loop. This is due to 
mod_timer from arming a timer that was already removed by del_timer during 
module unload.

This fixes bug:

The patch was cleanly cherry-picked from linux-next onto latest bionic 
tree and tested by me on a Cavium ThunderX2 system. Please refer to the bug
report for details on testing.
