NimBLEScan::clearResults doesn't actually release memory space

Hello, I found that when there are too many Bluetooth devices around, the memory usage continues to rise after scanning is turned on. I called "clearResults" to clean up, but...

用文件作为存储后端，有锁首次初始化时，_fdb_kv_load 中调用 fdb_kv_set_default 死锁

设了锁后，fdb_kvdb_init里调了一次db_lock： https://github.com/armink/FlashDB/blob/c1226f337a876f55c7c527634bb8729ae16b5c99/src/fdb_kvdb.c#L1757-L1758 再在 `_fdb_kv_load`里检查到失败计数`check_failed_count` 和`SECTOR_NUM`相等时，调用`fdb_kv_set_default`： https://github.com/armink/FlashDB/blob/c1226f337a876f55c7c527634bb8729ae16b5c99/src/fdb_kvdb.c#L1643-L1646 `fdb_kv_set_default`里又调一次db_lock： https://github.com/armink/FlashDB/blob/c1226f337a876f55c7c527634bb8729ae16b5c99/src/fdb_kvdb.c#L1392-L1399 用递归锁可以规避，但是文档中没有见到相关描述

仅仅只有一个setsockopt设置超时时间，在超时或者服务端连接主动断开的情况下，无法有效识别连接断开 建议增加通过 getsockopt 获取 SO_ERROR值，进行判断是 EAGAIN，还是 ENOTCONN 等其它连接异常错误， 以便提升连接丢失情况下的重连速度
