[PATCH -next] PCI: xilinx-xdma: Remove redundant dev_err()

[Yang Li]

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.

./drivers/pci/controller/pcie-xilinx-dma-pl.c:688:2-9: line 688 is redundant because platform_get_irq() already prints an error
./drivers/pci/controller/pcie-xilinx-dma-pl.c:702:2-9: line 702 is redundant because platform_get_irq() already prints an error
