features/trash : Notify CTR translator if an unlink happens to a file

This implementation is same as the posix_unlink_cbk() where CTR sends
a request during a unlink to send the number of links to the inode
and posix obliges sending it using the unwind xdata dict.
For Trash xlator a unlink is stat + mkdir(if parent is not present)
+ rename. And hence this is handled in trash_unlink_rename_cbk().
