[SCSI] bfa: AEN and byte alignment fixes.

Browse Source 
Replace enum types with int and rearrange the fields to fix some
alignment issue.

Local var ioc_attr is causing the stack to overflow, so removed the
usage of the local ioc_attr var and now invoking an API to return the
ioc_type.

Fix some AEN issues.
