bcache: replace snprintf in show functions with sysfs_emit
coccicheck complains about the use of snprintf() in sysfs show functions.
Fix the following coccicheck warning:
drivers/md/bcache/sysfs.h:54:12-20: WARNING: use scnprintf or sprintf.
Implement sysfs_print() by sysfs_emit() and remove snprint() since no one
uses it any more.
