Describe the bug
HS_EnableEventMonCmd() and HS_DisableEventMonCmd() have consecutive, mutually exclusive status checks.

Code snips

HS/fsw/src/hs_cmds.c

Lines 409 to 416 in 76915e9

	if (Status != CFE_SUCCESS)
	{
	CFE_EVS_SendEvent(HS_EVENTMON_LONG_SUB_EID, CFE_EVS_EventType_ERROR,
	"Event Monitor Enable: Error Subscribing to long-format Events,RC=0x%08X",
	(unsigned int)Status);
	}
	if (Status == CFE_SUCCESS)

HS/fsw/src/hs_cmds.c

Lines 465 to 472 in 76915e9

	if (Status != CFE_SUCCESS)
	{
	CFE_EVS_SendEvent(HS_EVENTMON_LONG_UNSUB_EID, CFE_EVS_EventType_ERROR,
	"Event Monitor Disable: Error Unsubscribing from long-format Events,RC=0x%08X",
	(unsigned int)Status);
	}
	if (Status == CFE_SUCCESS)

Expected behavior
Combine into an if/else - no need to do 2 evaluations.
