Translatable strings in nk6510.c

[Daniele Forsi]

these are the only strings in ./common/phones/nk6510.c that are passed 
to printf(); all others are passed to dprintf() or fprintf(); I think 
they should go to dprintf()

printf("SMS saving failed: Invalid location\n");
printf("SMS saving failed: Incorrect folder\n");
printf("SMS deleting failed: Invalid location?\n");
printf("SMS saving failed: Incorrect folder\n");
printf("Soft resetting....\n");
printf("Hard resetting....\n");
