wifi: nl80211: fix UHR capability validation

[ Upstream commit a140826caa2c14aa5a9a6990e514c5edbdb7eafd ]

The ieee80211_uhr_capa_size_ok() function returns a boolean,
but we need an error code here. Fix that.

Fixes: 072e6f7f416f ("wifi: cfg80211: add initial UHR support")
Cc: <stable+noautosel@kernel.org> # no drivers with UHR yet
