Input: hp_sdc - shut down kicker timer on module exit

hp_sdc_kicker() rearms hp_sdc.kicker with mod_timer() after scheduling the
tasklet.  The module exit path uses timer_delete_sync().  That waits for a
callback already running but can still leave the timer rearmed.

A callback can therefore leave the timer pending while hp_sdc_exit() tears
down the driver, allowing timer activity to access dismantled driver state.

Use timer_shutdown_sync() for final teardown.  It waits for a running
callback and prevents rearming after module exit begins.
