Bug#28556539 LOCK_ORDER: CYCLE INVOLVING BUF_POOL_FREE_LIST_MUTEX AND
BUF_POOL_ZIP_FREE_MUTEX
Problem:
The LOCK_ORDER tool reports a cycle in innodb mutex locks because of
incorrectly mapped key while creating a mutex. Because of this incorrect
mapping, the tool assumes there is a cycle between two mutexes
potentially leading to a deadlock.
Solution:
Replaced the incorrect key with the correct one
