Xiongfeng Wang 90ff030ca1 serial: pch: Fix PCI device refcount leak in pch_request_dma() ...

[ Upstream commit 8be3a7bf77 ]

As comment of pci_get_slot() says, it returns a pci_device with its
refcount increased. The caller must decrement the reference count by
calling pci_dev_put().

Since 'dma_dev' is only used to filter the channel in filter(), we can
call pci_dev_put() before exiting from pch_request_dma(). Add the
missing pci_dev_put() for the normal and error path.
