[SCSI] ses: add new Enclosure ULD
changes:
1. change char to unsigned char to avoid type change later.
2. preserve len for page1
3. need to move desc_ptr even the entry is not enclosure_component_device/raid.
so keep desc_ptr on right position
4. record page7 len, and double check if desc_ptr out of boundary before touch.
5. fix typo in subenclosure checking: should use hdr_buf instead.
