powerpc: Fix error path in kernel_thread function
The powerpc 32-bit and 64-bit kernel_thread functions don't properly
propagate errors being returned by the clone syscall. (In the case of
error, the syscall exit code returns a positive errno in r3 and sets
the CR0[SO] bit.)
This patch fixes that by negating r3 if CR0[SO] is set after the syscall.
