x86/kasan: Rename local CPU_ENTRY_AREA variables to shorten names

Rename the CPU entry area variables in kasan_init() to shorten their
names, a future fix will reference the beginning of the per-CPU portion
of the CPU entry area, and shadow_cpu_entry_per_cpu_begin is a bit much.

No functional change intended.
