tools/xenpaging: fix return value from xc_mem_paging_flush_ioemu_cache
While using xenpaging, "Error flushing ioemu cache" message will be
shown even if the "flush-cache" command is sent to xenstore correctly.
That is because xenpaging assumes xc_mem_paging_flush_ioemu_cache()
returns non-zero value when the operation fails. But
xc_mem_paging_flush_ioemu_cache() returns the return value from
xs_write() which is zero on error.
So, we should invert the return value from xs_write() and return -1 on
error, or 0 on success, like other xc_ functions.
