Common implementation of copy operation when OID is set
pOid->Flags (if used) controls when the source data may be truncated or padded on copy
Parameters:
        tOidDesc *pOid - descriptor of OID
        PVOID pDest    - buffer to receive data sent by NDIS
        ULONG ulSize   - size of data to copy
Return value:
    SUCCESS or NDIS error code if target buffer size is wrong
Rules:
 
PDEST       <>OK        SIZE    PAYLOAD SZ
NULL        any         n/a         any             fail
