This fixes the following sparse error:

drivers/staging/lustre/lustre/obdclass/llog_ioctl.c:388:39: error: incompatible types for operation (>)
drivers/staging/lustre/lustre/obdclass/llog_ioctl.c:388:39:    left side has type char *ioc_inlbuf2
drivers/staging/lustre/lustre/obdclass/llog_ioctl.c:388:39:    right side has type int
