New function reiserfs_tmpfile:
-Duplicate reiserfs_create
-Remove dquot_initialize (cf ext2/tmpfile)
-Remove add_entry code
-Add d_tmpfile generic call
-Add add_save_link (cf ext3/orphan_add)
reiserfs_link function:
-Add remove_save_link (cf ext3/orphan_del)
Saved link is removed in normal use (close)
cf reiserfs_evict_inode (reiserfsck is ok)
Note : This patch still requires reiserfs_link testing.
