cfg80211: check dev_set_name() return value
commit 59b179b48ce2a6076448a44531242ac2b3f6cef2 upstream.
syzbot reported a warning from rfkill_alloc(), and after a while
I think that the reason is that it was doing fault injection and
the dev_set_name() failed, leaving the name NULL, and we didn't
check the return value and got to rfkill_alloc() with a NULL name.
Since we really don't want a NULL name, we ought to check the
return value.
Fixes: fb28ad35906a ("net: struct device - replace bus_id with dev_name(), dev_set_name()")
Change-Id: Iecd16d788290c9d51a62c22a7c2784623aa0abc6
