perf session: create_kernel_maps should use ->host_machine

Using machines__create_kernel_maps(..., HOST_KERNEL_ID) it would create
another machine instance for the host machine, and since 1f626bc we have
it out of the machines rb_tree.

Fix it by using machine__create_kernel_maps(&self->host_machine)
directly.
