ocfs2: skip existing hole when removing the last extent_rec in punching-hole codes.
In the case of removing a partial extent record which covers a hole, current
punching-hole logic will try to remove more than the length of whole extent
record, which leads to the failure of following assert(fs/ocfs2/alloc.c):
5507 BUG_ON(cpos < le32_to_cpu(rec->e_cpos) || trunc_range > rec_range);
This patch tries to skip existing hole at the last attempt of removing a partial
extent record, what's more, it also adds some necessary comments for better
understanding of punching-hole codes.
