zhangdengyu 2afe81bf58 fix: 修复ffconf.h中宏FF_FS_LOCK设置不合理的问题 
方案描述：
1、修改FF_FS_LOCK宏定义为：#define FF_FS_LOCK  (CONFIG_NFILE_DESCRIPTORS + LOSCFG_MAX_OPEN_DIRS - MIN_START_FD)
2、其中各个宏的含义如下：
2.1、CONFIG_NFILE_DESCRIPTORS 在vfs_config.h文件中定义，表示打开文件描述符fd的最大数量
2.2、LOSCFG_MAX_OPEN_DIRS 在vfs_config.h文件中定义，表示打开目录最大数量
2.3、MIN_START_FD 在vfs_config.h文件中定义，表示保留的三个文件描述符fd：stdin,stdout,stderr

BREAKING CHANGE：
修复ffconf.h中宏FF_FS_LOCK设置不合理的问题
修改后的FF_FS_LOCK宏定义为：#define FF_FS_LOCK	(CONFIG_NFILE_DESCRIPTORS + LOSCFG_MAX_OPEN_DIRS - MIN_START_FD)

Far bc2af47971 fix: 修复FATFS中的BUG 
1. f_open接口在一些错误分支中未释放当前文件的锁，这会导致再次打开该文件时失败（EBUSY）;
2. f_mkfs未正确初始化返回值FRESULT fr的值，导致不可预知的返回值;
3. f_fdisk循环条件错误，导致死循环;

Far 97668edb4f feat: 三方库FatFs升级至r0.14a版本 
1. f_mkfs接口增强，现在除了簇大小，同时支持fat表数量，数据区对齐大小，根目录大小的设置。
2. 抽象部分内部接口find_volume/create_partition，提高代码复用度。
3. 修复一些bug。

Far 4094ea3cb8 fix: 修复FATFS中不同内部接口不支持FAT12/FAT16 FAT表结束标志 
FATFS内部接口中，仅对FAT32的FAT表结束符0x0FFFFFFF做了判断，而忽略了FAT12和FAT16的结束标志。
这会导致子在FAT12/FAT16中，部分功能异常。

Far eb9b7c3fe0 fix: statfs can't get f_bfree and f_bavail of a FAT12/FAT16 partition 
FAT12/FAT16 partition has no FSINFO sector storing the free cluster number,
so scanning the FAT is necessary to get the free clusters nums.
