[PATCH] scsi: myrs: Fix uninitialized variable

[YueHaibing <yuehaibing@huawei.com>]

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: 77266186397c ("scsi: myrs: Add Mylex RAID controller (SCSI interface)")
