fs: reiserfs: remove useless new_opts in reiserfs_remount
Since the commitc3d98ea082
("VFS: Don't use save/replace_mount_options if not using generic_show_options") eliminates replace_mount_options in reiserfs_remount, but does not handle the allocated new_opts, it will cause memory leak in the reiserfs_remount. Because new_opts is useless in reiserfs_mount, so we fix this bug by removing the useless new_opts in reiserfs_remount. Fixes:c3d98ea082
