scsi: isci: Convert snprintf() to sysfs_emit()

scsi: isci: Convert snprintf() to sysfs_emit()

Per filesystems/sysfs.rst, show() should only use sysfs_emit() or
sysfs_emit_at() when formatting the value to be returned to user space.

coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().

> ./drivers/scsi/isci/init.c:140:8-16: WARNING: please use sysfs_emit

No functional change intended
