Oilpan: HashTable::m_table should not be null in weak processing
Oilpan: HashTable::m_table should not be null in weak processing

Weak processing for a HashTable is registered only when the m_table of
the HashTable is not null. Thus HashTable::m_table should not be null
in the weak processing. This CL removes the unnecessary null check
and instead add an ASSERT about it.
