Yang Yingliang 5f58cad1e4 ocxl: fix pci device refcount leak when calling get_function_0()
get_function_0() calls pci_get_domain_bus_and_slot(), as comment
says, it returns a pci device with refcount increment, so after
using it, pci_dev_put() needs be called.

Get the device reference when get_function_0() is not called, so
pci_dev_put() can be called in the error path and callers
unconditionally. And add comment above get_dvsec_vendor0() to tell
callers to call pci_dev_put().

Fixes: 87db7579eb ("ocxl: control via sysfs whether the FPGA is reloaded on a link reset")
