I finally recompiled the kernel with the option
CONFIG_CFG80211_WEXT=y
This casues me to replace the lib80211,cgf80211,libertas & libertas_sdio
drivers. To be sure I also replaced the rfkill* drivers.
iwconfig now can detect wlan0, which is normal I think..
Most of the ioctl error messages are disappeared (just one is shown..):
ioctl[SIOCSIWPMKSA]: Invalid argument
And I don't understand what this error refers to..
The network is shown as before, unencrypted.
I post the output of the wpa_execution from shell:

Could the problem come from another driver?
