[SCSI] libsrp: fix memory leak in srp_ring_free()

This patch fixes a memory leak in the libsrp function srp_ring_free().
It is not documented whether or not this function should free the ring
pointer itself. But the source code of the callers of this function
(srp_target_alloc() and srp_target_free()) makes it clear that
srp_ring_free() should deallocate the ring pointer itself. Furthermore,
the patch below makes srp_ring_free() deallocate all memory allocated by
srp_ring_alloc().

This patch affects the ibmvstgt driver, which is the only in-tree driver
that calls the srp_ring_free() function (indirectly).
