Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386:
move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through
cpu_init() but was still reset immediately after in linux-user and
bsd-user. Clean this up.

Similarly it is also reset after cpu_copy(), but that's a bug of its own.

 v2 -> v3:
 * Don't touch cpu_copy() at all, only fixing the double reset
   and not changing cpu_copy() behavior.

 v1 -> v2:
 * First move cpu_reset() into cpu_copy() before dropping x86 reset.

Applied this stripped-down version to qom-cpu:
