ACPI: fix resource check message 

printk("%pR",...)
is for formatting struct resource only.
But the list built up in drivers/acpi/osl.c uses it's own struct:
struct acpi_res_list {}

Without this patch you can see wrongly formatted resources (SMRG is of IO type):

ACPI: resource 0000:00:1f.3 [io  0x0400-0x041f] conflicts with AC
      PI region SMRG [mem 0x00000400-0x0000040f 64bit pref disabled]
