Invalid code in fts_savepoint_release() in InnoDB

          Description

          There's a clearly incorrect code in storage/innobase/fts/fts0fts.cc in MariaDB 10.0.1 tarball. On line 5348 it has:

          			/* Swap the entries. */
			memcpy(&temp, last, sizeof(temp));
			memcpy(last, prev, sizeof(*last));
			memcpy(prev, &temp, sizeof(prev));

          The last statement doesn't copy full fts_savepoint_t struct from temp to *prev, because the last parameter should be sizeof(*prev).
