[PATCH] RISC-V: KVM: Remove unnecessary 'ret' assignments

[Qiang Ma]

If the program can execute up to this point, indicating that
kvm_vcpu_write_guest() returns 0, and the actual value of
SBI_SUCCESS is also 0. At this time, ret does not need to be
assigned a value of 0.

Fixes: e309fd113b9f ("RISC-V: KVM: Implement get event info function")
