s390/dasd: fix gcc 8 stringop-truncation warning
drivers/s390/block/dasd_alias.c:711:2: warning: 'strncpy' output truncated
before terminating nul copying 4 bytes from a string of the same length
[-Wstringop-truncation]
strncpy((char *) &cqr->magic, "ECKD", 4);
Replace strncpy to int as a buffer with memcpy.
