Thanks for the explanation.  However, the code change size is no excuse
for providing workarounds rather than the actual fix.

A possible way to handle such case would be keeping a list of
pathname:lease_key pairs inside the inode, so in smb2_compound_op() you
could look up the lease key by using @dentry.  I'm not sure if there's a
better way to handle it as I haven't looked into it further.
