[PATCH] btrfs-progs: fix gcc8 default build warning caused by '-Wformat-truncation'

When using gcc8 compiles utils.c, it complains as below: utils.c:852:45: warning: '%s' directive output may be truncated writing up to 4095 bytes into a region of size 4084 [-Wformat-truncation=] snprintf(path, sizeof(path), "/dev/mapper/%s", name);
