error-injection: remove EI_ETYPE_NONE
Patch series "error-injection: Clarify the requirements of error injectable functions". Patches for clarifying the requirement of error injectable functions and to remove the confusing EI_ETYPE_NONE. This patch (of 2): Since the EI_ETYPE_NONE is confusing type, replace it with appropriate errno. The EI_ETYPE_NONE has been introduced for a dummy (error) value, but it can mislead people that they can use ALLOW_ERROR_INJECTION(func, NONE). So remove it from the EI_ETYPE and use appropriate errno instead.
