    iwlwifi: remove CMD_WANT_SKB flag if send_cmd_sync failure

    In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
    we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
    to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
    the cmd comes in later, it will possibly set an invalid address. Thus
    it causes an invalid memory access.

    This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.
