Change i_gen in UFS to an unsigned type.
In UFS, i_gen is a random generated value and there is not way for
it to be negative. Actually, the value of i_gen is just used to
match bit patterns and it is of not consequence if the values are
signed or not.
Following other filesystems, set it to unsigned and use it as such,
