[PATCH v3 14/22] common/idpf: update in PTP message validation

[Soumyadeep Hore]

When the message for getting timestamp latches is sent by the driver,
number of latches is equal to 0. Current implementation of message
validation function incorrectly notifies this kind of message length as
invalid.
