Nothing.

As usual when the module is in use.

That would be insane.

Not IMO. That a feature may fail is not a reason to not implement it.
Otherwise removing a module would not even be implemented, because it
may fail when the module is in use.

Just as usual : if there is at least one active loop device beyond the
new limit -> fail the write and do nothing. However, I believe users
would mostly need the feature to increase the number of loop devices,
not to reduce it : "oops, I just need more loop devices !"
