Masami Hiramatsu (Google) 49d2de8635 fprobe: Fix to allocate entry_data_size buffer with rethook instances 
commit 6572786006 upstream.

Fix to allocate fprobe::entry_data_size buffer with rethook instances.
If fprobe doesn't allocate entry_data_size buffer for each rethook instance,
fprobe entry handler can cause a buffer overrun when storing entry data in
entry handler.
