[SCSI] use scmd_id(), scmd_channel() throughout code
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
