Clive Lin 5f55836ab4 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 8d36694245 ("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.
