Subject: [PATCH] pci: fix device registration on FreeBSD

[ upstream commit 24a535796824049fab8570d0b29e658470375876 ]

The FreeBSD implementation wasn't registering new devices
with the device framework on start up. However, common
code attempts to unregister them on shutdown which causes
a SEGFAULT. This fix makes the FreeBSD code do the same
thing as the Linux code for registration.

Fixes: 13a1317d3ba7 ("pci: create device list and fallback on its members")
