quota: fix parents caching during build ancestry

In build ancestry, we get the list of parents for a file,
these parents are cached in inode ctx.
This caching is not happening because posix is not setting
d_stat information in the leaf node entry
This patch fixes the issue

Inode-ctx is not updated with new parent when
rename performed on same directory.
This patch fixes the issue

There is a possibility of caching stale entries,
consider below example:
1) build_ancestry invoked on a file
2) rename is invoked on the same file
3) buils_ancestry prepared entries of old parent
4) rename completed and in cbk old parent is replaced with
       new parent in inode ctx
5) now build_ancestry cbk adds old parent to inode ctx

In this patch we also remove stale entries in writev and fallocate
