Nikolay Borisov 31fe243a63 btrfs: promote debugging asserts to full-fledged checks in validate_super 
commit aefd7f7065567a4666f42c0fc8cdb379d2e036bf upstream.

Syzbot managed to trigger this assert while performing its fuzzing.
Turns out it's better to have those asserts turned into full-fledged
checks so that in case buggy btrfs images are mounted the users gets
an error and mounting is stopped. Alternatively with CONFIG_BTRFS_ASSERT
disabled such image would have been erroneously allowed to be mounted.
