4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx>
commit a44074f14ba1ea0747ea737026eb929b81993dc3 upstream.
Although it is possible to let SRP I/O continue if a reconnect
results in a reduction of the number of channels, the current
code does not handle this scenario correctly. Instead of making
the reconnect code more complex, consider this as a reconnection
failure.
