[CRIU] [PATCH] remote: Fix incorrect passing of port option

[Radostin Stoyanov]

The `port` option for image-cache and image-proxy is converted twice.
- 1st when the argument is provided from the user (in crtools.c)
- 2nd when the value is provided set to `sin_port` (in img-remote.c)
Unfortunately, the 2nd conversion reverses the 1st one.

Example:

	#include <stdio.h>
	#include <arpa/inet.h>
	#include <stdlib.h>

	int main()
	{
	    printf("%d\n", htons(atoi("1234"))); /* 53764 */
	    printf("%d\n", htons(htons(atoi("1234")))); /* 1234 */
	    return 0;
	}
