iwinfo: fix nl80211 phy lookup without platform prefix

Commit d9b20a6f35 (SVN r48426) changed the
mac80211 phy lookup logic to strip the platform/ directory component from
the phy path specification.

Fix iwinfo to follow that logic by trying to lookup phys both with and
without "platform/" prefix.
