cephadm: Delete the unnecessary error line in open_ports

In #39020, d9fbd7e is cherry picked from 70722a2. there is no bug in 70722a2,
but there is a bug in d9fbd7e. It seems that the unnecessary error line was added during cherry picking.
So error only occurs in octopus branch.
This commit directly fixes issue in octopus branch instead of cherry picking
since cherry picking from 70722a2 has already been applied to octopus branch.

This commit deletes the unnecessary error line added in d9fbd7e.
In d9fbd7e, the parameter verbose_on_failure was removed in call.
However, the unnecessary line that uses verbose_on_failure was
added in open_ports and so error occurs.
