geo-replication: fix memory leak in gsyncd
1. leak in str2argv() function: char *strdup(const char *s); The strdup() function returns a pointer to a new string which is a duplicate of the string s. Memory for the new string is obtained with malloc(3), and can be freed with free(3). so when using strdup, user has to take care of freeing the memory allocated by strdup library function. 2. leak in main() function: str2argv() function calls calloc and allocates memory pointed to argv, after return from str2argv() memory pointed to argv has to be cleaned in main(). This patch is to fix 2 memory leaks mentioned above.
