wlan: revoke the reassoc ioctl command from iwpriv interface.

currently we have support for the reassoc through supplicant
CLI as well as through iwpriv. We only need to provide reassoc
command through supplicant as all the roaming algorithms depend
on the supplicant for key derivation. Hence the reassoc
command through iwpriv is being revoked.
