rtsx_usb_ms: use schedule_timeout_idle() in polling loop
First version of this patch has already been posted to LKML by Ben Hutchings ~6 months ago, but no further action were performed. Ben's original message: : rtsx_usb_ms creates a task that mostly sleeps, but tasks in : uninterruptible sleep still contribute to the load average (for : bug-compatibility with Unix). A load average of ~1 on a system that : should be idle is somewhat alarming. : : Change the sleep to be interruptible, but still ignore signals.
