ext4: use ext4_grpblk_t more extensively
unsigned short is potentially too small to track blocks within a group; today it is safe due to restrictions in e2fsprogs but we have _lo / _hi bits for group blocks with the intent to go up to 32 bits, so clean this up now. There are many more places where we use unsigned/int/unsigned int to contain a group block but this should at least fix all the short types. I added a few comments to the struct ext4_group_info definition as well. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
