[PATCH 1/2] RedfishPkg/RedfishRestExDxe: fix driver binding stop issue.

["Nickle Wang" <nicklew@nvidia.com>]

RedfishRestExDriverBindingStop() does not uninstall service
binding protocol and release resource because:
- RestExDestroyChildEntryInHandleBuffer() does not remove entry
when NetIsInHandleBuffer() return false. So the linked list
is not empty.
- When NumberOfChildrenis 0, binding stop function return in the
NetLibGetNicHandle() condition check and never reach to the reset
of code in driver binding stop.
