After r254627, the deupdate() started writing the directory entries to
disk.  That has a side effect of corrupting the "." entries names on
rename, since the call to createde() in the msdosfs_rename() sets the
de_Name to the target name.  If any change to the directory attributes
is performed, the wrong name is written back to the on-disk direntry
on update.

Overwrite the de_Name for the directories on rename to correct the dot
name.

Pass radix head ptr along with rte to rtexpunge().
Rename rtexpunge to rt_expunge().
Remove additional fib checks from rtalloc1_fib.
It looks like current consumers are either unaware
of MRT (and uses RT_DEFAULT_FIB implicitly) or
know what thay are doing, In latter case they
will be either hit by KASSERT or ESCRH will be returned
due to NULL rnh.
