When sending a query to the device returns with a timeout error,
we clear the corresponding bit in the DOORBELL register but
we don't clear the outstanding_request field as we should.
This patch fixes this bug.

Sometimes queries from the device might return a failure so it is
recommended to retry sending the query, before giving up.
This change adds a wrapper to retry sending a query attribute,
in cases where we need to wait longer, before we continue,
or before reporting a failure.

UFS flag query requests may fail sometimes due to timeouts etc.
Add a wrapper function to retry up to 10 times in case of such
failure, similar to retries being made for attribute queries.
