Summary

In case LKPI_80211_HW_CRYPTO we convert from LinuxKPI cipher_suites
to net80211 ic_cryptocaps fields. For WLAN_CIPHER_SUITE_CCMP we
accidentally returned the bit number instead of the shifted value
which leads to ieee80211_crypto_newkey() setting IEEE80211_KEY_SWCRYPT,
which in turned lead to us trying to decode the frame again despite
HW had already done it. This was found out of a discussion in D43634.
