FSP/CONSOLE: Disable notification on unresponsive consoles
Commit fd6b71fc fixed the situation where ipmi console was open (hvc0) but got
data on different console (hvc1).
During FSP R/R OPAL closes all consoles. After R/R complete FSP requests to
open hvc1 and sends data on this. If hvc1 registration failed or not opened in
host kernel then it will not read data and results in RCU stalls.
Note that this is workaround for older kernel where we don't have separate irq
for each console. Latest kernel works fine without this patch.
