rxrpc: Miscellaneous fixes
Here are some miscellaneous AF_RXRPC fixes for more stuff found by Sashiko[1][2]:
(1) Fix ACKALL handling by adding two more call states to simplify when
ACKs are valid.
(2) Fix connection leak from AF_RXRPC recvmsg userspace OOB handling.
(3) Fix double unlock in AF_RXRPC recvmsg userspace OOB handling.
(4) Fix AFS preallocate charge to flush the waitqueue after unlistening
the socket so that any charging thread that does manage to get started
will be waited for before socket destruction.
(5) Fix AFS OOB notify handling to cancel in-progress OOB notification
handling and then to flush the workqueue it's on.
(6) Fix handling of apparent reply reception before initial transmission
starts in client call.
(7) Fix OOB challenge leak in cleanup on notification failure.
(8) Fix infinite loop in recvmsg if OOB packet available, but no calls.
(9) Fix notify vs recvmsg race where notify thinks the call is already
queued.
(10) Fix MSG_PEEK call leak for calls with no content.
(11) Fix rxrpc_rotate_tx_window() to check that there's something in the Tx
buffer before attempting to rotate it.
