x86: return correct error code from child_rip in x86_64 entry.S

Right now register edi is just cleared before calling do_exit.
That is wrong because correct return value will be ignored.
Value from rax should be copied to rdi instead of clearing edi.

AK: changed to 32bit move because it's strictly an int
