Fix the following warning:
drivers/serial/8250_pci.c: In function "pciserial_resume_one":
drivers/serial/8250_pci.c:1998: warning: ignoring return value of "pci_enable_device", declared with attribute warn_unused_result
Signed-off-by: Jean Delvare <khali@xxxxxxxxxxxx>

As a side note, I'm curious why the call to pci_enable_device() is
conditioned by priv being set. I'm also not sure if additional cleanups
should be performed if an error occurs.
