can: pcan_usb: fix wrong memcpy() bytes length
Fix possibly wrong memcpy() bytes length since some CAN records received from
PCAN-USB could define a DLC field in range [9..15].
In that case, the real DLC value MUST be used to move forward the record pointer
but, only 8 bytes max. MUST be copied into the data field of the struct
can_frame object of the skb given to the network core.

can: peak_usb: fix hwtstamp assignment
The skb->tstamp is set to the hardware timestamp when available in the USB
urb message. This leads to user visible timestamps which contain the 'uptime'
of the USB adapter - and not the usual system generated timestamp.
Fix this wrong assignment by applying the available hardware timestamp to the
skb_shared_hwtstamps data structure - which is intended for this purpose.

can: peak_usb: PCAN-USB specific part: fix little endian usage
That patch fixes some bad usage of two little-endian variables, which lead to
some warning/error when building the peak_usb driver.
