[PATCH] ntdll: Honour alertable argument in NtContinue.

Since 7a71f98640bf, NtContinue always performs alertable wait, meaning 
that dispatch_exception can cause APC to be invoked, ignoring that 
alertable is FALSE.

I found it while debugging a win16 application, which crashed in APC 
unexpectedly invoked when returning from an emulated DOS call. The 
problem is more likely to happen in win16, where we have a lot of 
exceptions, but it's more generic.
