MDEV-17820 Assertion failed on instant DROP COLUMN

Browse Source 
btr_cur_pessimistic_insert(): Do not attempt to convert the
metadata BLOB to external storage if it has already been converted.
It could have been converted by btr_cur_pessimistic_update().
Relax some over-zealous assertions.

dtuple_convert_big_rec(): Assert that the metadata BLOB has
not been converted yet.
