[PATCH] um: fix ptrace build error

[Richard Weinberger]

Both 0a3d763 and 9b05a69 broke the um build.
This patch fixes the issues.

0a3d763 introduced the undeclared variable "datavp".
The patch seems completely untested. :-(

9b05a69 changed arch_ptrace()'s signature but did not
update um/include/asm/ptrace-generic.h.
