hash: separate param checks in hash create func
Checks
Commit Message
Separated name, entries and key_len parameter checks in
rte_hash_create(). Also made the error messages more
informative/verbose to help with debugging. Also added myself to the
mailing list.

I had name set to NULL in the parameters I was passing to
rte_hash_create() and the error message I got didn't specify which
parameter was invalid.
