Fix some potential memory leaks in error handling branches while
iterating xattr entries.
Such information is useful.
For example, function ubifs_tnc_remove_ino()
forgets to free pxent if it exists. Similar problems also exist in
ubifs_purge_xattrs(), ubifs_add_orphan() and ubifs_jnl_write_inode().
Can an other wording variant be a bit nicer?
Thanks for reminding, I will improve this description.
I suggest to avoid the specification of duplicate function calls
(also for the desired exception handling).
Will it be helpful to add a few jump targets?

I've thought about using "goto err_tag_2" in kill_xattrs code block to
release prev xent, but later it needs to jump to 'out_release tag‘ for
releasing previously requested memory, which can clutter the code. It
seems that two consecutive 'goto tags' will make the code less readable.
