Wrap a highly common idiom. Makes the code easier to read, helps pave the way for sdev->{id,channel} removal, and adds a token that can easily by grepped-for in the future. There are a couple sdev_id() and scmd_printk() updates thrown in as well. Rejections fixed up and Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
