Pavel Pisa 7b57e6d434 hw/net/can/sja1000: fix bug for single acceptance filter and standard frame

A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found
by Linux kernel testing because it uses dual filter mode (MOD_AFM = 0)
and leaves falters fully open.

The problem has been noticed by Grant Ramsay when testing with Zephyr
RTOS which uses single filter mode.
