[PATCH] fs: reiserfs: free new_opts in reiserfs_remount

[Dongliang Mu <mudongliangabcd@xxxxxxxxx>]

Since the commit c3d98ea08291 ("VFS: Don't use save/replace_mount_options
if not using generic_show_options") eliminates replace_mount_options
in reiserfs, but did not handle the allocated new_opts,
it will cause memory leak in the reiserfs_remount.

Fix this by freeing new_opts in the reiserfs_remount temporarily.
