[SCSI] ibmvscsi: Add support for capabilities MAD
Add support to ibmvscsi for the capabilities MAD. This command gets sent to the Virtual I/O server prior to login in order to communicate client capabilities. Additionally it returns information regarding capabilities that the server supports. The two main capabilities communicated in this MAD are related to partition migration and client reserve. Client reserve allows for SCSI-2 reservations to be sent to virtual disks which are backed by physical LUNs and will result in the reservation being sent to the physical LUN.
