Modified Files:
        src/sys/dev/pci: pci_usrreq.c

Log Message:
make sure PCI_IOC_DRVNAMEONBUS doesn't access NULL pointers.

hopefully fixes PR#55744.  it's not entirely clear why this does
not affect most systems, as there's usually some PCI devices that
do not have attached drivers, eg:

006:00:0: AMD Family17h/7xh Reserved SPP (non-essential instrumentation, subclass 0x00)

on my system i'm testing on.

XXX: pullup-8, pullup-9.
