Chungkai Yang 9a2c57fd32 PM: QoS: Restore support for default value on frequency QoS
commit 3a8395b565 upstream.

Commit 8d36694245 ("PM: QoS: Add check to make sure CPU freq is
non-negative") makes sure CPU freq is non-negative to avoid negative
value converting to unsigned data type. However, when the value is
PM_QOS_DEFAULT_VALUE, pm_qos_update_target specifically uses
c->default_value which is set to FREQ_QOS_MIN/MAX_DEFAULT_VALUE when
cpufreq_policy_alloc is executed, for this case handling.

Adding check for PM_QOS_DEFAULT_VALUE to let default setting work will
fix this problem.

Fixes: 8d36694245 ("PM: QoS: Add check to make sure CPU freq is non-negative")
