e2fsck: use ext2_ino_t instead of ino_t

The ino_t type is defined by the system header files, and may be
anything from an unsigned int, unsigned long, or an unsigned long
long.  So where we are referring to an ext2/ext3/ext4 inode number, we
should use ext2_ino_t to avoid this ambiguity, especially when passing
an inode number to a printf-style function.

This was detected via a compiler warning on MacOS, but it's
potentially a real bug, since it can cause an error message to print a
garbled inode number.
