security/vboot: Remove struct vboot_working_data

Browse Source 
After CB:36808, CB:36844 and CB:36845, all fields except buffer_offset
were removed from struct vboot_working_data. Since buffer_offset is used
to record the offset of the workbuf relative to the whole structure, it
is no longer needed.

This patch removes the structure, and renames vboot_get_working_data()
to vboot_get_workbuf().
