um: fix ptrace build error

Both commits 0a3d763f1a68 ("ptrace: cleanup arch_ptrace() on um") and
9b05a69e0534 ("ptrace: change signature of arch_ptrace()") broke the um
build.  This patch fixes the issues.

0a3d763f1a68 introduced the undeclared variable "datavp".  The patch seems
completely untested.  :-(

9b05a69e0534 changed arch_ptrace()'s signature but did not update
um/include/asm/ptrace-generic.h.
