MLK-14930-1 cmd: sata: Fix sata init and stop issue
When sata stop is executed, the sata_curr_device is not reset to -1, so
any following sata commands will not initialize the sata again and cause
problem.
Additional, in sata init implementation, the sata_curr_device should be updated,
otherwise sata will be initialized again when doing other sata commands like
read/write/info/part/device.
