fs core fixes (was Re: TFTP driver changes)

[Eugeny S. Mints]

Please, have a look at my letter to Till with CC to you.
There is the patch to unmount.c: in addition to your
comments for unmount.c below there are: order of unmount_h
and fs_unmounmt_h calls changed and  call
rtems_filesystem_freenode for (&fs_root_loc) added in a
proper(as it seems to me) place in unmoun function.
Call to free fs_root_loc.mt_entry->mt_fs_root in unmount
also removed.

Are you going to apply patch for these files? It seems to me
the patch
arose disscuusion. For example, I think changes to open and
close are wrong because of ideology. ( see appropriate
letters, please )

It seems, this is the right way.
