In function 'activate_lsp', rather than hard-coding the
short atom header(0x83), we need to let the function
'add_short_atom_header' append the header based on the
parameter being appended.

The paramete has been defined in Section 3.1.2.1 of
https://trustedcomputinggroup.org/wp-content/uploads/TCG_Storage-Opal_Feature_Set_Single_User_Mode_v1-00_r1-00-Final.pdf
