Subject: [PATCH] PCI: dra7xx: Fix return value in case of error

In function 'dra7xx_pcie_init_irq_domain', the pattern used to check and
return error is:

   if (!var) {
      dev_err(...);
      return PTR_ERR(var);
   }

So the returned value in case of error is always 0, which means 'success'.
Change it to return -ENODEV instead.
