[RESEND,02/11] s390/dasd: Use sysfs_emit() over sprintf()

Commit Message

From: Jan Höppner <[e-mail]>

sysfs_emit() should be used in show() functions. There are still a
couple of functions that use sprintf().
Replace outstanding occurrences of sprintf() in all show() functions
with sysfs_emit().
