[PATCH] spi: use sysfs_emit() for printing statistics and add trailing newline

[Heiner Kallweit <hkallweit1@gmail.com>]

Use dedicated function sysfs_emit() that does some extra checking,
e.g. to ensure that no more than PAGESIZE bytes are written.
In addition add a trailing newline to the output, that makes it
better readable from the console.
