DevPath - A pointer to a device path data structure
Returns:
If the memory for the device path is successfully allocated, then a pointer to the
new device path is returned. Otherwise, NULL is returned.

Routine Description:
Convert a device node to its text representation.
Arguments:
DeviceNode - Points to the device node to be converted.
DisplayOnly - If DisplayOnly is TRUE, then the shorter text representation
of the display node is used, where applicable. If DisplayOnly
is FALSE, then the longer text representation of the display node
is used.
AllowShortcuts - If AllowShortcuts is TRUE, then the shortcut forms of text
representation for a device node can be used, where applicable.
Returns:
A pointer - a pointer to the allocated text representation of the device node.
NULL - if DeviceNode is NULL or there was insufficient memory.
