Maurizio Lombardi 5dd6c49339 scsi: iscsi: set auth_protocol back to NULL if CHAP_A value is not supported
If the CHAP_A value is not supported, the chap_server_open() function
should free the auth_protocol pointer and set it to NULL, or we will leave
a dangling pointer around.

[   66.010905] Unsupported CHAP_A value
[   66.011660] Security negotiation failed.
[   66.012443] iSCSI Login negotiation failed.
