[PATCH 22/31] scsi: Inline scsi_init_command()

[Bart Van Assche <bart.vanassche@sandisk.com>]

The two drivers that use the per-device command list, namely aacraid
and dpt_i2o, expect that that list contains only SCSI commands and
no task management functions. Hence only call scsi_add_cmd_to_list()
from the block layer prep callback functions and not from
scsi_ioctl_reset().
