scsi: target: Replace strncpy() with strscpy() in VPD dump functions

Replace the deprecated[1] strncpy() with strscpy() in
transport_dump_vpd_proto_id(), transport_dump_vpd_assoc(),
transport_dump_vpd_ident_type(), and transport_dump_vpd_ident().

All four functions follow the same pattern: a local
buf[VPD_TMP_BUF_SIZE] (254 bytes) is zeroed with memset(), populated
via sprintf()/snprintf() (always NUL-terminated), then conditionally
copied to p_buf with strncpy(). The p_buf destination is used as a
C string by all callers in target_core_configfs.c: strlen(buf) and
sprintf(page+len, "%s", buf) to build sysfs output.

NUL-padding is not required: callers in target_core_configfs.c
pre-zero p_buf with memset() or initializer before calling these
functions, and consume p_buf only as a NUL-terminated C string via
strlen() and "%s", never exposing trailing bytes.

No behavioral change: the source buf is always NUL-terminated and
shorter than VPD_TMP_BUF_SIZE, so strscpy() produces identical output.
