can: f81604: f81604_handle_can_bus_errors(): fix {rx,tx}_errors statistics
[ Upstream commit d7b916540c2ba3d2a88c27b2a6287b39d8eac052 ]
The f81604_handle_can_bus_errors() function only incremented the receive
error counter and never the transmit error counter, even if the ECC_DIR
flag reported that an error had occurred during transmission.
Increment the receive/transmit error counter based on the value of the
ECC_DIR flag.
Fixes: 88da17436973 ("can: usb: f81604: add Fintek F81604 support")
