[PATCH] frv: pci-frv: fix build warning

[Sudip Mukherjee]

The build of frv defconfig gives warning:

arch/frv/mb93090-mb00/pci-frv.c:176:5: warning:
        ignoring return value of 'pci_assign_resource',
                declared with attribute warn_unused_result

Just print an error message to silence the warning. We can not do much
here on error.
