Karsten Graul 3a523807f0 net/smc: Fix NULL pointer dereference in smc_pnet_find_ib()
[ Upstream commit d22f4f977236f97e01255a80bca2ea93a8094fc8 ]

dev_name() was called with dev.parent as argument but without to
NULL-check it before.
Solve this by checking the pointer before the call to dev_name().

Fixes: af5f60c7e3d5 ("net/smc: allow PCI IDs as ib device names in the pnet table")
