bnxt_re/lib: increment psn in case of 0 length packets
    
    If application posts a 0 length packet, post send routine
    is skipping to increment the psn number. This will cause
    PSN number to go out of sync and eventually connection would
    terminate due to sequence error.
    
    post_send routine must increment the psn number by 1 even
    for zero length packets.
