The xc_ptrace API relies on errno for passing success/failure indication
back to callers.  However, mapping operations that fall back on legacy
APIs may leave errno set to a non-zero result even thought the operation
is successful.  This patch resets errno after successful map operations
so that xc_ptrace doesn't inadvertently return a failure.
