Nick Khyl 0481042738 ipn/ipnserver: fix a deadlock in (*Server).blockWhileIdentityInUse
If the server was in use at the time of the initial check, but disconnected and was removed
from the activeReqs map by the time we registered a waiter, the ready channel will never
be closed, resulting in a deadlock. To avoid this, we check whether the server is still busy
after registering the wait.

Fixes #14655
