Subject: [PATCH net-next 4/8] be2net: reorder fields in be_eq_obj structure

Re-order fields in struct be_eq_obj to ensure that .napi field begins
at start of cache-line. Also the .adapter field is moved to the first
cache-line next to .q field and 3 fields (idx,msi_idx,spurious_intr)
and the 4-bytes hole to 3rd cache-line.
