scsi: libsas: fix memory leak in sas_smp_get_phy_events()

commit 4a491b1ab11ca0556d2fda1ff1301e862a2d44c4 upstream.

We've got a memory leak with the following producer:

while true;
do cat /sys/class/sas_phy/phy-1:0:12/invalid_dword_count >/dev/null;
done

The buffer req is allocated and not freed after we return. Fix it.
