    ktls: Post receive errors on partially closed sockets.
    
    If an error such as an invalid record or one whose decryption fails is
    detected on a socket that has received a RST then ktls_drop() could
    ignore the error since INP_DROPPED could already be set.  In this case
    soreceive_generic hangs since it does not return from a KTLS socket
    with pending encrypted data unless there is an error (so_error) (this
    behavior is to ensure that soreceive_generic doesn't return a
    premature EOF when there is pending data still being decrypted).
    
    Note that this was a bug prior to
    69542f26820b7edb8351398b36edda5299c1db56 as tcp_usr_abort would also
    have ignored the error in this case.
