Bug #110251 change information about get_lock error message

Description:
MySQL   enforces a maximum length on lock names of 64 characters.
when lock_name length is more than  64 characters  in  get_lock,
error message is below:
ERROR 3057 (42000): Incorrect user-level lock name 'xxxxxxxxxxxxxxxxxxx';

Then message is Incorrect lock name, not  about length.

Change the message about error lock  name length is more  convenient  when trouble shooting 

How to repeat:
mysql>  select get_lock('wdnmqkno-dadas--1231-3@efs_01-najvcn-1212-ccasc@mcm-sddd-danjskn111@c0c0-mmm-lll',1);
ERROR 3057 (42000): Incorrect user-level lock name 'wdnmqkno-dadas--1231-3@efs_01-najvcn-1212-ccasc@mcm-sddd-danjskn111@c0c0-mmm-lll'.

Suggested fix:
change error message is more  convenient  
mysql>  select get_lock('wdnmqkno-dadas--1231-3@efs_01-najvcn-1212-ccasc@mcm-sddd-danjskn111@c0c0-mmm-lll',1);
ERROR 3057 (42000): Exceed user-level lock name limit 'wdnmqkno-dadas--1231-3@efs_01-najvcn-1212-ccasc@mcm-sddd-danjskn111@c0c0-mmm-lll'.
