Petr Gusev 3655879f48 error_injection: release waiters when injection is disabled
When an error injection is disabled (via disable() or disable_all()),
any handlers currently suspended in wait_for_message() must be woken up
so they can proceed instead of hanging until timeout.

Add a 'disabled' flag to injection_shared_data. When disable() or
disable_all() is called, set the flag and broadcast the condition
variable. The wait_for_message() predicate checks the flag and returns
true immediately, letting the handler continue.

This makes disable() atomic with respect to releasing waiters: it both
wakes up blocked handlers and removes the injection from the enabled
map in one call. This avoids races that would occur with separate
message_injection() + disable() calls — message_injection() after
disable() fails because the injection is already gone, and
disable() after message_injection() risks a new handler hitting the
injection between the two calls.

Concrete example: test_unfinished_writes_during_shutdown pauses
barrier_and_drain RPC handlers via wait_for_message. During shutdown,
the test calls disable_injection() to simultaneously release the
paused handler and prevent any new barrier_and_drain RPCs from
getting stuck.
