[PATCH 2/2] PCI: switchtec: Remove useless assignments in switchtec_dev_read()

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

Some switchtec_dev_read() error cases assign to "rc", then branch to "out".
But the code at "out" never uses "rc".  Drop the useless assignments.  No
functional change intended.
