Bjorn Helgaas ddc10938e0 PCI: switchtec: Return -EFAULT for copy_to_user() errors 
switchtec_dev_read() didn't handle copy_to_user() errors correctly: it
assigned "rc = -EFAULT", but actually returned either "size", -ENXIO, or
-EBADMSG instead.

Update the failure cases to unlock mrpc_mutex and return -EFAULT directly.
