parport: rework procfs handlers to take advantage of the new buffer

The buffer coming from higher up the stack has an extra byte to handle
the NULL terminator in the string.  Instead of using a temporary buffer
to sprintf into and then copying into the buffer, just scnprintf
directly into the buffer and update lenp as appropriate.
