[PATCH] PM / QoS: Export dev_pm_qos_update_user_latency_tolerance

[Kai-Heng Feng]

From: Andrew Lutomirski <luto at kernel.org>

BugLink: https://bugs.launchpad.net/bugs/1666401

nvme wants a module parameter that overrides the default latency
tolerance.  This makes it easy for nvme to reflect that default in
sysfs.
