LTF keyseed required flag is set only for newly created PASN
peer. This value is filled from the security mode value received
the PASN peer create request event from the firmware.
If PASN peer already exists, then the peer is just added to the
peer list and secure LTF keyseed required flag is not updated.
This leads to wrong sequence of commands going to firmware.
Expected sequence: Install TK -> Set LTF keyseed -> PASN Auth
STATUS.
Observed Sequence: Install TK -> PASN Auth status -> Set LTF
keyseed -> PASN Auth status.
So set the is_ltf_keyseed required flag for already existing
PASN peer also
