fixed the following sparse warning by adding proper cast:
drivers/staging//lustre/lustre/obdclass/obd_config.c:1055:74: warning: incorrect type in argument 2 (different address spaces)
drivers/staging//lustre/lustre/obdclass/obd_config.c:1055:74:    expected char const [noderef] <asn:1>*<noident>
drivers/staging//lustre/lustre/obdclass/obd_config.c:1055:74:    got char *[assigned] sval
