dm zoned: fix potential NULL dereference in dmz_do_reclaim()

This function is supposed to return error pointers so it matches the
dmz_get_rnd_zone_for_reclaim() function.  The current code could lead to
a NULL dereference in dmz_do_reclaim()

Fixes: b234c6d7a703 ("dm zoned: improve error handling in reclaim")
