MDEV-37354 : SIGSEGV in Wsrep_server_service::release_high_priority_service | discard_streaming_applier

Browse source 
This issue seems to be already fixed. However, to avoid future problems:

Wsrep_server_service::release_storage_service
  Add assertion that storage service is not nullptr and
  contains thd. In production binaries add guard to
  not use nullptr.

Wsrep_server_service::release_high_priority_service
  Add assertion that high_priority service is not nullptr and
  contains thd. In production binaries add guard to
  not use nullptr.

wsrep_is_BF_lock_timeout
  Remove printing of record lock because its page might
  not be latched leading to assertion in multi-master
  testing.
