From: Colin Ian King <[email protected]>
Currently, the while loop will iterate until a matching name is found
or until the id pointer wraps around to NULL (the latter is incorrect).
The end of a pci_epf_device_id table is terminated with zero'd entries
for name and driver_data, so can change the while loop to iterate while
the first character in the name is a non-zero character.

Fixes: 9e9d6eb48623 ("PCI: endpoint: Add an API to get matching
"pci_epf_device_id")
