MDEV-19695 Import tablespace doesn't work with ROW_FORMAT=COMPRESSED encrypted tablespace

Browse Source 
Problem:
=======
fil_iterate() writes imported tablespace page0 as it is to discarded
tablespace. Space id wasn't even changed. While opening the tablespace,
tablespace fails with space id mismatch error.

Fix:
====
fil_iterate() copies the page0 with discarded space id to imported
tablespace.
