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%. Signed-off-by: "Yann E.

+ help
+ The number of blocks on the filesystem (as a percentage of the
+ total number of blocksi), that are reserved for use by root.
+ Traditionally, this has been 5%, and all ext-related tools still
+ default to reserving 5% when creating a new ext filesystem.
