spi: Revert "spi: Insert the missing pci_dev_put()before return"

Commit 8a0ec8c2d736 ("spi: Insert the missing pci_dev_put()before
return") added two uses of pci_dev_put() with an uninitialized dma_dev,
resulting in the following compiler warnings (or errors with
CONFIG_WERROR) when building with clang:

  drivers/spi/spi-pxa2xx-pci.c:150:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized]
    150 |                 pci_dev_put(dma_dev);
        |                             ^~~~~~~
  drivers/spi/spi-pxa2xx-pci.c:228:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized]
    228 |                 pci_dev_put(dma_dev);
        |                             ^~~~~~~

Commit 609d7ffdc421 ("spi: pxa2xx-pci: Balance reference count for PCI
DMA device") added a call to pci_dev_put() via
devm_add_action_or_reset() in case of failures, so the recent change was
incorrect for multiple reasons. Revert it altogether.
