idpf: Don't hard code napi_struct size

Browse Source 
commit 49717ef01ce1b6dbe4cd12bee0fc25e086c555df upstream.

The sizeof(struct napi_struct) can change. Don't hardcode the size to
400 bytes and instead use "sizeof(struct napi_struct)".

[Yifei: In Linux-6.12.y, it still hard code the size of napi_struct,
adding a member will lead the entire build failed]
