Without this fix the zdb printouts of ZIL data blocks look full of FF
due to printf() handling its arguments as int by default.
Here is the output before the fix
TX_WRITE len 4136, txg 1093817, seq 149231
foid 4242, offset 0, length f68
G FFFFFF8EFFFFFF87FFFFFF91FFFFFFCC 1c
FFFFFFAFFFFFFFC9FFFFFFBAZ FFFFFFC3
And the same after the fix
TX_WRITE len 4136, txg 1093817, seq 149231
foid 4242, offset 0, length f68
G 8E8791CC 1cAFC9BAZ C3
