Fix gdbserver-xen support on older kernels.

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.
