can: etas_es58x: replace es58x_device::rx_max_packet_size by usb_maxpacket()

Browse source

The field rx_max_packet_size of struct es58x_device in nothing else
than usb_endpoint_descriptor::wMaxPacketSize and can be easily
retrieved using usb_maxpacket(). Also, rx_max_packet_size being used a
single time, there is no merit to cache it locally.

Remove es58x_device::rx_max_packet_size and rely on usb_maxpacket()
instead.
