x86/traps: Fix #DE Oops message regression

commit 5f1ec1fd32252af5130dac23b5542e8e66fe0bcb upstream.

The conversion of #DE to the idtentry mechanism introduced a change in the
Ooops message which confuses tools which parse crash information in dmesg.

Remove the underscore from 'divide_error' to restore previous behaviour.

Fixes: 9d06c402
