When the SMC client perform CLC handshake, it will check whether
the clc header type is correct in receiving SMC_CLC_ACCEPT packet.
The specific invoking path is as follows:
__smc_connect
smc_connect_clc
smc_clc_wait_msg
smc_clc_msg_hdr_valid
smc_clc_msg_acc_conf_valid
Therefore, the smc_connect_check_aclc interface invoked by
__smc_connect does not need to check type again.
