Bug #16154 DD: Duplicate LOGFILE GROUP creates results in error unkown by perror

Description:
Test Cases:

CREATE LOGFILE GROUP lg1
ADD UNDOFILE './var/tmp/undofile.dat'
INITIAL_SIZE 16M
UNDO_BUFFER_SIZE = 1M
ENGINE=NDB;

CREATE LOGFILE GROUP lg1
ADD UNDOFILE './var/tmp/undofile.dat'
INITIAL_SIZE 16M
UNDO_BUFFER_SIZE = 1M
ENGINE=NDB;

Test shows error:
 failed: 1502: Failed to create LOGFILE GROUP

perror shows:

./extra/perror --ndb 1502
OS error code 1502:  No message slogan found (please report a bug if you get this error code): Unknown: Unknown

../extra/perror  1502
Illegal error code: 1502

How to repeat:
See above

Suggested fix:
added error so that perror can pick it up.

Added:
failed: 1507: Failed to alter: CREATE UNDOFILE

../extra/perror  1507 Illegal error code: 1507
../extra/perror --ndb 1507 OS error code 1507:  No message slogan found (please report a bug if you get this error code): Unknown: Unknown

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

I made it so that show warnings will show ndberror
