[PATCH] x86: bogus tls from gdt

The per-CPU initialization code is copying in bogus data into
thread->tls_array.  Note that it copies &per_cpu(cpu_gdt_table, cpu), not
&per_cpu(cpu_gdt_table, cpu)[GDT_ENTRY_TLS_MIN).  That is totally broken
and unnecessary.  Make the initialization explicitly NULL.
