Revert "iwinfo: update to git HEAD"

This reverts commit f1620630e9f3407780ddc554361841f05c996c49.

This update introduces potentially remote exploitable buffer overreads
in IE parsing logic.

It also breaks the ABI without introdcing SOVERSION library versioning.

Furthermore, HT information is incorrectly added for non-HT BSSes.
