Yann E. MORIN 3286a4d6aa fs/ext2: allow reserving zero block for root
The previous default, zero, just meant "use the default value of the
filesystem generator", which happened to be 5% (the traditional value
for all ext-creating tools we've ever seen).

So, change the new default accordingly to 5%.
