x86: return correct error code from child_rip in x86_64 entry.S
patch 1c5b5cfd290b6cb7c67020ef420e275f746a7236 in mainline.
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
