NetworkPkg: Fix invalid pointer for DNS response token on erroredk2-stable202111
Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=3719
This issue is introduced by the commit 43d7e607.
Token->RspData.H2AData is de-allocated on error but it is not
set to NULL. HTTP module attempts to free again and cause assert.
