MDEV-17230: encryption_key_id from alter is ignored by encryption threads

Browse Source 
Background: Used encryption key_id is stored to encryption metadata
i.e. crypt_data that is stored on page 0 of the tablespace of the
table. crypt_data is created only if implicit encryption/not encryption
is requested i.e. ENCRYPTED=[YES|NO] table option is used
fil_create_new_single_table_tablespace on fil0fil.cc.

Later if encryption is enabled all tables that use default encryption
mode (i.e. no encryption table option is set) are encrypted with
default encryption key_id that is 1. See fil_crypt_start_encrypting_space on
fil0crypt.cc.

ha_innobase::check_table_options()
	If default encryption is used and encryption is disabled, you may
        not use nondefault encryption_key_id as it is not stored anywhere.
