Handle missing jremrefs when a directory is renamed overtop of

another, deleting it.  If the directory is removed, UFS always need to
remove the .. ref, even if the ultimate ref on the parent would not
change. The new directory must have a new journal entry for that ref.
Otherwise journal processing would not properly account for the
parent's reference since it will belong to a removed directory entry.

Change ufs_rename()'s dotdot rename section to always
setup_dotdot_link(). In the tip != NULL case SUJ needs the newref dependency
allocated via setup_dotdot_link().

Stop setting isrmdir to 2 for newdirrem() in softdep_setup_remove().
Remove the isdirrem > 1 checks from newdirrem().
