Clear integrity failure bit in PendingScript on release

Clear integrity failure bit in PendingScript on release

This fixes a bug where a script loaded after a previous script failed
due to an integrity failure would also fail to load. This is because the
PendingScript object was reused for the new script resource, and we
failed to clear out the m_integrityFailure bit. This simply sets that to
false when the old script resource is released.
