darwin: Fix invalid GetPipePropertiesV3 argument

GetPipePropertiesV3 seems to require that the bVersion field of the
properties argument be set before calling it:
"Version of the structure. Currently kUSBEndpointPropertiesVersion3.
Need to set this when using this structure"

Not doing so results in an invalid argument error.

Closes #744
