i82875p_edac: Drop redundant call to pci_get_device()

The first call to pci_get_device() in i82875p_probe1() is useless. The
result is immediately reset at the beginning of
i82875p_setup_overfl_dev(), which then issues the same
pci_get_device() call. Dropping the redundant call avoids a device
reference leak.
