Alter Sequence allows MAXVALUE one over max value

Tested in 20150114 build.

Alter Sequence command allows MAXVALUE set to 9223372036854775807, that is one over allowed max value. See the example below:

SQL>CREATE SEQUENCE sq1;

--- SQL operation complete.

SQL>showddl SEQUENCE sq1;

CREATE SEQUENCE TRAFODION.HSU.SQ1
  START WITH 1 /* NEXT AVAILABLE VALUE 1 */
  INCREMENT BY 1
  MAXVALUE 9223372036854775806
  MINVALUE 1
  CACHE 25
  NO CYCLE
  LARGEINT
;

SQL>alter sequence seq1 maxvalue 9223372036854775807;

--- SQL operation complete.

SQL>create seq2 maxvalue 9223372036854775807;

*** ERROR[1576] MAXVALUE value is greater than maximum allowed for this sequence. [2015-01-14 21:24:50]
