x86/entry/32: Rename 'error_code' to 'common_exception'
The 'error_code' label is awkwardly named, especially when it shows up in a stack trace. Move it to its own local function and rename it to 'common_exception', analagous to the existing 'common_interrupt'. This also makes related stack traces more sensible.
