scsi: myrs: Fix uninitialized variable

Browse Source 
drivers/scsi/myrs.c: In function 'myrs_log_event':
drivers/scsi/myrs.c:821:24: warning: 'sshdr.sense_key' may be used uninitialized in this function [-Wmaybe-uninitialized]
  struct scsi_sense_hdr sshdr;

If ev->ev_code is not 0x1C, sshdr.sense_key may be used uninitialized. Fix
this by initializing variable 'sshdr' to 0.

Fixes: 7726618639 ("scsi: myrs: Add Mylex RAID controller (SCSI interface)")
