bz235299: Fix quota do_list operation hang

This is the filesystem part of the patches to fix this bz. There are additional userland patches (gfs2_quota, libgfs2) for the complete solution. This patch adds a new field qu_ll_next to the gfs2_quota structure. This field allows us to create linked lists of quotas in the ondisk quota inode. Instead of scanning through the entire sparse quota file for valid quotas, we can now simply walk through the user and group quota linked lists to perform the do_list operation.
