arch/frv/mb93090-mb00/pci-frv.c: fix build warning

Browse Source 
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.
