[PATCH v3] scsi/bfa: use designated initializers

[Kees Cook <keescook@chromium.org>]

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. This also initializes the
array members using the enum used to look up __port_action entries.

v3:
- drop bfa_module_s changes, since that has been removed entirely; hch.
- init array with enum literals; hch.
