net: xilinx: axienet: Fix IRQ coalescing packet count overflow
If coalesce_count is greater than 255 it will not fit in the register and
will overflow. This can be reproduced by running
# ethtool -C ethX rx-frames 256
which will result in a timeout of 0us instead. Fix this by checking for
invalid values and reporting an error.
