This doesn't make code cleaner.
What about resource deallocation after AllocateZeroPool (sizeof
(EFI_HTTP_RESPONSE_DATA)) for the common case?
I guess this resource deallocation was added for this and there are a
lot of 'goto ON_EXIT;' after original AllocateZeroPool call.
I would suggest to remove this `if (EFI_ERROR (Status)) {` block at all.
As I can see, the only callers of this function are
RedfishPkg//PrivateLibrary/RedfishLib/edk2libredfish/src/service.c and
edk2-redfish-client//RedfishClientPkg/PrivateLibrary/RedfishLib/edk2libredfish/src/service.c.
And both use the same pattern of an explicit response data
deallocation (RestConfigFreeHttpMessage() call) in case of error
status returned.
I.e. caller is responsible for the response data deallocation as it owns it.
