[PATCH v1 21/22] chnet: ring: Bump max_entry to 2G

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

Make it able to handle bigger ring size. I have tested this with 2G
entry and it works fine. Didn't manage to test chnet though, only
nop SQEs as I don't have that much memory to run chnet with 2G ring
size.
