libsupport: don't try accessing the project quota for 128 byte inodes

If the file system has 128 byte inode, it's not possible to access its
project quota id, since the inode is too small.  So prevent a
potential out-of-bounds read in get_qid().

The problem was found by valgrind and American Fuzzy Lop.
