[PATCH] PCI: designware: remove unused variable

[Arnd Bergmann]

A cleanup patch removed the only use of the 'ret' variable
in wr_conf but forgot to remove the variable:

pci/host/pcie-designware.c: In function 'dw_pcie_wr_conf':
pci/host/pcie-designware.c:683:6: warning: unused variable 'ret' [-Wunused-variable]

This cleans that part up as well.
