e2e: do not use Failf() to abort tests in a go-routine (rbd)
There are several go-routines where Failf() is called, which will cause a Golang panic inside the Ginko test framework. Instead of aborting the go-routine, capture the error and check for failures once all go-routines have finished. The CephFS tests have been updated already, this changs only affects the RBD tests. Updates: #1359 Signed-off-by: Niels de Vos <ndevos@redhat.com>
