xen-blkback: do not leak mode property
commit 9d092603cc306ee6edfe917bf9ab8beb5f32d7bc upstream.
"be->mode" is obtained from xenbus_read(), which does a kmalloc() for
the message body. The short string is never released, so do it along
with freeing "be" itself, and make sure the string isn't kept when
backend_changed() doesn't complete successfully (which made it
desirable to slightly re-structure that function, so that the error
cleanup can be done in one place).
