Fix inconsistent naming of IP type enum

[jwrosewell]

The enum for representing an IP address type is inconsistently named.

The word evidence needs to be removed from the typedef.

typedef enum e_fiftyone_degrees_ip_evidence_type {
	FIFTYONE_DEGREES_IP_TYPE_INVALID = 0, /**< Invalid IP address */
	FIFTYONE_DEGREES_IP_TYPE_IPV4 = 4, /**< An IPv4 address */
	FIFTYONE_DEGREES_IP_TYPE_IPV6 = 6, /**< An IPv6 address */
} fiftyoneDegreesIpType;

typedef enum e_fiftyone_degrees_ip_type {
	FIFTYONE_DEGREES_IP_TYPE_INVALID = 0, /**< Invalid IP address */
	FIFTYONE_DEGREES_IP_TYPE_IPV4 = 4, /**< An IPv4 address */
	FIFTYONE_DEGREES_IP_TYPE_IPV6 = 6, /**< An IPv6 address */
} fiftyoneDegreesIpType;
