Describe the bug
A few cases of consecutive, mutually exclusive status checks in CS.

Code snips

CS/fsw/src/cs_init.c

Lines 64 to 71 in ed72e15

	if (Result != CFE_SUCCESS)
	{
	CFE_EVS_SendEvent(CS_INIT_SB_SUBSCRIBE_HK_ERR_EID, CFE_EVS_EventType_ERROR,
	"Software Bus subscribe to housekeeping returned: 0x%08X", (unsigned int)Result);
	}
	if (Result == CFE_SUCCESS)
	{

CS/fsw/src/cs_init.c

Lines 112 to 120 in ed72e15

	if (ResultInit != CFE_SUCCESS)
	{
	CS_AppData.HkPacket.EepromCSState = CS_STATE_DISABLED;
	CFE_EVS_SendEvent(CS_INIT_EEPROM_ERR_EID, CFE_EVS_EventType_ERROR,
	"Table initialization failed for Eeprom: 0x%08X", (unsigned int)ResultInit);
	}
	if (ResultInit == CFE_SUCCESS)
	{

Expected behavior
Combine into if/else constructs - clearer and reduces evaluations.
