Merge branch 'be2net-small-structures-clean-up'

Ivan Vecera says:

====================
be2net: small structures clean-up

The series:
- removes unused / unneccessary fields in several be2net structures
- re-order fields in some structures to eliminate holes, cache-lines
  crosses
- as result reduces size of main struct be_adapter by 4kB
====================
