Subject: scsi_sysfs: Fix queue_ramp_up_period return code

From: Peter Oberparleiter <oberpar@linux.vnet.ibm.com>

commit 863e02d0e173bb9d8cea6861be22820b25c076cc upstream.

Writing a number to /sys/bus/scsi/devices/<sdev>/queue_ramp_up_period
returns the value of that number instead of the number of bytes written.
This behavior can confuse programs expecting POSIX write() semantics.
Fix this by returning the number of bytes written instead.
