watchdog: ziirave_wdt: Fix incorrect use of ARRAY_SIZE

Browse source 
Both memset() and ziirave_firm_write_block_data() expect length in
bytes as an argument, not a number of elements in array. It just
happens that in this particular case both values are equal. Modify the
code to use sizeof() instead.
