From: Sergey Matyukevich <redacted> [ Upstream commit 35da3fe63b8647ce3cc52fccdf186a60710815fb ] On disconnect wireless core attempts to remove all the supported keys. Following cfg80211_ops conventions, firmware returns -ENOENT code for the out-of-bound key indexes. This is a normal behavior, so no need to report errors for this case.
