Commit d97dc8a0 separated the non-command code into its own file which caused variable sata_curr_device can not be set to a correct value.
Before commit d97dc8a0, variable sata_curr_device can be set correctly in sata_initialize(). After commit d97dc8a0, sata_initialize() is moved out to its own file. Accordingly, sata_curr_device is removed from sata_initialize() too. This caused sata_curr_device never gets a chance to be set properly which prevent other command from being executed.
This patch sets variable sata_curr_device properly.
