spi: dw-dma: decrease reference count in dw_spi_dma_init_mfld()

Browse source

[ Upstream commit 804313b64e ]

pci_get_device() will increase the reference count for the returned
pci_dev. Since 'dma_dev' is only used to filter the channel in
dw_spi_dma_chan_filer() after using it we need to call pci_dev_put() to
decrease the reference count. Also add pci_dev_put() for the error case.
