Bug#44164: TL_WRITE has no description in lock_descriptions[]

Browse source 
The problem was that new lock types were being added without a
corresponding description. Since the lock types (enum values)
are used as indices to the description array, the descriptions
could be shifted depending on the lock type. The solution is to
ensure that every lock type has a correspondent description.

include/thr_lock.h:
  Add warning.
sql/sql_test.cc:
  Update lock descriptions.
