Subject: [PATCH -next] PCI: endpoint: Remove redundant dev_err().

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.

Eliminate the following warning:
./drivers/pci/endpoint/functions/pci-epf-mhi.c:362:2-9: line 362 is redundant because platform_get_irq_byname() already prints an error
