Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188541. In function
rsxx_pci_probe(), variable st takes the return value. Its value should
be negative on failures. However, the value of st is 0 even if the call
to create_singlethread_workqueue() returns a NULL pointer. This patch
fixes the bug by assigning -ENOMEM to st when the call fails.
