dict_table_t::init_instant(): Remove a bogus assertion

Browse Source 
This is basically re-applying 8fe34dd45f39b22ae0134532b5b5247e4e8620fe.
Assertions about ROW_FORMAT not changing during instant ALTER TABLE can
fail if the MariaDB and InnoDB data dictionaries get out of sync,
for example if innodb_default_row_format is used instead of specifying
ROW_FORMAT in the CREATE TABLE statement. In this case, ALTER_OPTIONS
would not necessarily be set. We would create the ctx->instant_table
with a ROW_FORMAT based on altered_table. When applying it to
the ctx->old_table, we will preserve the original ROW_FORMAT.
