PM: QoS: Add check to make sure CPU latency is non-negative
CPU latency should never be negative, which will be incorrectly high
when converted to unsigned data type.
Commit 8d36694245f2 ("PM: QoS: Add check to make sure CPU freq is
non-negative") makes sure CPU frequency is non-negative to fix incorrect
behavior in freqency QoS.
Add an analogous check to make sure CPU latency is non-negative so as to
prevent this problem from happening in CPU latency QoS.
