can: SJA1000 add missing spin_lock_init() 



As remarked by Sam Ravnborg the spin_lock variable, that has been introduced
in commit 57c8a456 ("can: Fix SJA1000 command
register writes on SMP systems") has not been initialized properly.

This patch adds the initialization to allow spinlock debugging.
