An error msg that is not easy to understand during the status check

[Lance52259]

Hi team,

When an unexpected state occurs, the provider throws an error message that is not easy to understand. Mainly beceuse this unexpected status does not appear in the targetStatus array of the status check function. In addition, these states are normal intermediate states, so no exception is thrown. In this case, the following response with a nil error is generated. e.g.:

unexpected state 'Unregistering', wanted target 'DELETED'. last error: %!s(<nil>)

Currently, the following resources have found this problem:

Number	Resource Name	Unexpected status	CRUD	Has fixed
1	huaweicloud_apig_instance	Unregistering	D	N
2	huaweicloud_sfs_access_rule	error	C	N
3	huaweicloud_cce_node	Synchronized	C	N
4	huaweicloud_vpnaas_site_connection_v2	DELETING	D	N
4	huaweicloud_dms_kafka_instance	ERROR	D	N

Note: Do not close this issue until all resources are repaired.

Best regards!
