scsi: qla2xxx: Avoid possible run-time warning with long model_num
The prior strlcpy() replacement of strncpy() here (which was later replaced with strscpy()) expected pinfo->model_num (and pinfo->model_description) to be NUL-terminated, but it is possible it was not, as the code pattern here shows vha->hw->model_number (and vha->hw->model_desc) being exactly 1 character larger, and the replaced strncpy() was copying only up to the size of the source character array. Replace this with memtostr(), which is the unambiguous way to convert a maybe not-NUL-terminated character array into a NUL-terminated string. Fixes: 527e9b704c3d ("scsi: qla2xxx: Use memcpy() and strlcpy() instead of strcpy() and strncpy()") Reviewed-by: Martin K.
