Subject: [PATCH -next] rsxx: fix error return code in rsxx_pci_probe()

From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn>

Fix to return -ENOMEM in the create_singlethread_workqueue() error handling
case instead of 0, as done elsewhere in this function.

Introduced by commit a3299ab18591d36ad5622f5064619123c439b779.
(rsxx: Individual workqueues for interruptible events.)
