This patch fixes up the computation of nbinodes which would go
negative due to an int overflow issue when nbblocks > 2Meg for
a 2Gig or greater filesystem.

The computation is now done as a float equation, since both nbblocks
and bytes_per_inode are no floats, and then cast to int by assignment.

int tmp_nbinodes = nbblocks * BLOCKSIZE / bytes_per_inode;
