[SCSI] megaraid: fix mega_internal_command oops
scsi_cmnd->cmnd was changed from a static array to a pointer post
2.6.25. It breaks mega_internal_command():
static int
mega_internal_command(adapter_t *adapter, megacmd_t *mc, mega_passthru *pthru)
{
...
scb = &adapter->int_scb;
memset(scb, 0, sizeof(scb_t));
scmd = &adapter->int_scmd;
memset(scmd, 0, sizeof(Scsi_Cmnd));
sdev = kzalloc(sizeof(struct scsi_device), GFP_KERNEL);
scmd->device = sdev;
scmd->device->host = adapter->host;
scmd->host_scribble = (void *)scb;
scmd->cmnd[0] = MEGA_INTERNAL_CMD;
mega_internal_command() uses scsi_cmnd allocated internally so
scmd->cmnd is NULL here. This patch adds a static array for cdb to
adapter_t and uses it here. This also uses
scsi_allocate_command/scsi_free_command, the recommended way to
allocate struct scsi_cmnd since the driver might use sense_buffer in
struct scsi_cmnd.
