block: drbd: remove a stay unlock in __drbd_send_protocol()

There are two callers of this function and they both unlock the mutex so
this ends up being a double unlock.

drbd: set BDI_CAP_STABLE_WRITES, we want page content to NOT change during write-out

When the feature was introduced, it was made "default".
But then it soon was changed to "opt-in", which we apparently missed.

drbd: skip spurious timeout (ping-timeo) when failing promote

If you try to promote a Secondary while connected to a Primary
and allow-two-primaries is NOT set, we will wait for "ping-timeout"
to give this node a chance to detect a dead primary,
in case the cluster manager noticed faster than we did.

But if we then are *still* connected to a Primary,
we fail (after an additional timeout of ping-timout).

This change skips the spurious second timeout.

Most people won't notice really,
since "ping-timeout" by default is half a second.

But in some installations, ping-timeout may be 10 or 20 seconds or more,
and spuriously delaying the error return becomes annoying.

drbd: don't retry connection if peers do not agree on "authentication" settings

emma: "Unexpected data packet AuthChallenge (0x0010)"
 ava: "expected AuthChallenge packet, received: ReportProtocol (0x000b)"
      "Authentication of peer failed, trying again."

Pattern repeats.

There is no point in retrying the handshake,
if we expect to receive an AuthChallenge,
but the peer is not even configured to expect or use a shared secret.

drbd: fix print_st_err()'s prototype to match the definition

print_st_err() is defined with its 4th argument taking an
'enum drbd_state_rv' but its prototype use an int for it.

Fix this by using 'enum drbd_state_rv' in the prototype too.
