BUG#29806 - binlog_innodb.test creates a server log

Browse Source 
Stopping mysql server could result in an entry in mysql error
file: "InnoDB: Error: MySQL is freeing a thd".

This happened because InnoDB assumes that the server will never
call external_lock(F_UNLCK) in case external_lock(READ/WRITE)
failed.

Prior to this patch we haven't had strict definition whether
external_lock(F_UNLCK) must be called in case external_lock(READ/WRITE)
fails.

This patch states that we never call external_lock(F_UNLCK) in case
external_lock(READ/WRITE) fails.


mysql-test/suite/binlog/t/disabled.def:
  Re-enabled binlog_innodb and binlog_killed tests.
sql/ha_ndbcluster.cc:
  Restore handler state in case external_lock() failed.
sql/ha_partition.cc:
  Do not call external_lock(F_UNLCK) in case external_lock(READ/WRITE) failed.
sql/lock.cc:
  Do not call external_lock(F_UNLCK) in case external_lock(READ/WRITE) failed.
storage/myisammrg/myrg_locking.c:
  Restore handler state in case external_lock() failed.
