[PATCH 05/10] PCI: host-generic: Remove dev_err() when handing an error from platform_get_irq()

There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.

This change is as per suggestion from Coccinelle:

  drivers/pci/controller/pcie-tango.c:277:2-9: line 277 is redundant
  because platform_get_irq() already prints an error
