nifm: Fix returned buffer size of GetClientId (#2036)

This PR fix an issue introduced on last IPC rewrite PRs where some returned buffer size have to be explicit now.
`GetClientId` without an explicit buffer size return some garbage to the guest and then `nifm` service crashes because of a wrong ClientId. It's fixed now.

Horizon Chase Turbo and Doom regression are fixed now.  (Probably some other games too)
