[SCSI] gdth: Add missing call to gdth_ioctl_free
Add missing call to gdth_ioctl_free before aborting.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression buf,ha,len,addr,E;
@@
buf = gdth_ioctl_alloc(ha, len, FALSE, &addr)
... when != false buf != NULL
when != true buf == NULL
when != \(E = buf\|buf = E\)
when != gdth_ioctl_free(ha, len, buf, addr)
*return ...;
// </smpl>
