bugs/core: Reorganize fields in the first line of WARNING output, add ->comm[] output

With the introduction of the condition string as part of the 'file'
string output of kernel warnings, the first line has become a bit
harder to read:

   WARNING: CPU: 0 PID: 0 at [ptr == 0 && 1] kernel/sched/core.c:8511 sched_init+0x20/0x410

Re-order the fields by importance (higher to lower), make the 'at' meaningful
again, and add '->comm[]' output which is often more valuable than a PID.

Also, remove the 'PID' prefix - in combination with comm it's clear what it is.

These changes make the output only slightly longer:

   WARNING: [ptr == 0 && 1] kernel/sched/core.c:8511 at sched_init+0x20/0x410 CPU#0: swapper/0

While adding more information and making it better organized.
