arch/arm/src/stm32h7: Remove broken FDCAN filter ioctl stubs.

Browse source 
The SIOCxCANxxFILTER cases in fdcan_netdev_ioctl() call
stm32_addextfilter(), stm32_delextfilter(), stm32_addstdfilter() and
stm32_delstdfilter(), none of which exist anywhere in the tree. The
block only ever compiled because no stm32h7 config enables
NETDEV_CAN_FILTER_IOCTL; enabling it breaks the link. The commands now
fall through to the existing -ENOTSUP default, which is also what a
caller observed before.
