KVM: extend EMULATE_EXIT_USER to support different exit reasons
Currently the instruction emulator code returns EMULATE_EXIT_USER and common code initializes the "run->exit_reason = .." and "vcpu->arch.hcall_needed = .." with one fixed reason. But there can be different reasons when emulator need to exit to user space. To support that the "run->exit_reason = .." and "vcpu->arch.hcall_needed = .." initialization is moved a level up to emulator.
