Release hash-table memory after screen-content decision

Screen-content decision did not deallocate the hashed motion estimation
table. As a result, the encoder could potentially create MAX_LAG_BUFFERS
many hash_tables.

This CL deallocates the hash-table after screen-content decision to
limit memory usage. Furthermore, this CL also fixes an assertion that
should have caught this.

Tests on m2.mkv shows that memory foot-print has reduced from ~498MB to
~236MB.
