CAN driver retuirn code patch

The following patch defines the error code to be returned by
cyg_io_set_config() for the config keys CYG_IO_SET_CONFIG_CAN_RANGE_FILTER and
CYG_IO_SET_CONFIG_CAN_MASK_FILTER if no buffers or filters are available

The function shall return -ENOSPC to indicate that there are no filters
available. At the moment the only implementation that uses these keys (LPC2xxx
CAN driver) returns -EPERM. But -EPERM is also returned if it is not possible
to configure filters because message filterings is deactivated
(CYGNUM_CAN_MSGBUF_RX_FILTER_ALL). So with the new return code it is possible
for the application to identify the exact reason why message filter
configuration failed.
