PM / QoS: return -EINVAL for bogus strings
commit 2ca30331c156ca9e97643ad05dd8930b8fe78b01 upstream.
In the current code, if the user accidentally writes a bogus command to
this sysfs file, then we set the latency tolerance to an uninitialized
variable.
Fixes: 2d984ad132a8 (PM / QoS: Introcuce latency tolerance device PM QoS type)
