hle_ipc: Remove std::size_t casts where applicable

These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.

Now that the flags are enabled, we can freely change the interface to
make these unnecessary.
