MIPS: wrppmc: Fix build of PCI code.

  CC      arch/mips/wrppmc/pci.o
/home/ralf/src/linux/linux-mips/arch/mips/wrppmc/pci.c: In function ‘gt64120_pci_init’:
/home/ralf/src/linux/linux-mips/arch/mips/wrppmc/pci.c:41:6: error: variable ‘tmp’ set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors

This warning exists in gcc 4.6.0 and newer.  Kernels 2.6.40 and newer use
-Wunused-but-set-variable to suppress it.
