Adjust ia64_linux_xfer_partial following to_xfer_partial API change.

Browse source 
ia64-linux-nat.c no longer compiles because ia64_linux_xfer_partial
no longer matches the to_xfer_partial prototype.  This patch fixes
the problem by adjusting it accordingly.

gdb/ChangeLog:

        * ia64-linux-nat.c (ia64_linux_xfer_partial): Add function
        documentation.  Adjust prototype to match the target_ops
        to_xfer_partial method.  Adjust implementation accordingly.
