[PATCH] uml: fix usage of kernel_errno in place of errno

To avoid conflicts, in kernel files errno is expanded to kernel_errno, to
distinguish it from glibc errno.  In this case, the code wants to use the libc
errno but the kernel one is used; in the other usage, we return errno in place
of -errno in case of an error.
