Richard Yao 66a38fd10a Linux: Suppress clang static analyzer warning in zfs_remove() 
Clang's static analyzer points out that if we fail to find an extended
attribute directory, but somehow find it when calculating delete_now and
delete_now is true, we will have a NULL pointer dereference when we try
to unlink the extended attribute directory.

I am not sure if this is possible, but if it is, I do not see a sane way
of handling this other than rolling back the transaction and retrying.
For now, let us do an VERIFY_IMPLY(). If this trips, it will stop the
transaction from committing, which will prevent an attribute directory
leak.
