[PATCH 02/16] PR: Handle PASN Authentication frame TX status with retransmission

[Peddolla Harshavardhan Reddy]

Handle PASN Authentication frame 1 TX status in
pr_pasn_auth_tx_status() by retransmitting the stored frame when it
is not acknowledged. Extend the initiator auth work timeout from 2
seconds to 10 seconds via a new PR_PASN_AUTH_TIMEOUT constant to
provide sufficient window for retransmissions to succeed.
