serdev: Refine several error or debug messages

Browse Source 
Refine several dev_err() and dev_dbg() messages to solve:

// hardcoded device name
dev_dbg(dev, "...dev_name_str...")

// repeated device name since dev_dbg() also prints it as prefix
dev_err(dev, "...%s...", dev_name(dev))

// not concise as dev_err(dev, "...%d...", err)
dev_err(dev, "...%pe...", ERR_PTR(err))
