[RESEND,v7,1/3] ring: fix unmatched type definition and usage

  Field 'flags' of struct rte_ring is defined as int type. However,
it is used as unsigned int. To ensure consistency, change the
type of flags to unsigned int. Since these two types has the
same byte size, this change is not an ABI change.

Fixes: af75078fece3 ("first public release")

This triggers a warning in our ABI checker:

      in pointed to type 'struct rte_ring' at rte_ring_core.h:119:1:
        type size hasn't changed
        1 data member change:
          type of 'int flags' changed:
            entity changed from 'int' to compatible type 'typedef uint32_t' at stdint-uintn.h:26:1
              type name changed from 'int' to 'unsigned int'
              type size hasn't changed

I guess we were supposed to merge this in 23.11, sorry about this.

How can we proceed?

How about we drop this amendment (patch 1/3) for now?
