x86: traps_xx: refactor die() like in x86_64

Make the diff between the traps_32.c and traps_64.c a bit smaller.

Change traps_32.c to look more like traps_64.c:
 - move lock information to file scope
 - split out oops_begin() and oops_end() from die()
 - increment nest counter in oops_begin

Only whitespace change in traps_64.c

No functional changes intended.
