At the thread-safe configuration (_FS_REENTRANT == 1), an unexpected
operation to the volume can result a wrong volume lock. For example,
f_open() ==> media change ==> f_close(), in this case the volume gets
left locked and following function calls to the volume will be locked
out until a forced initialization of the volume by f_mount(). To solve
this problem, apply this patch to the ff.c.

f_unlink function does not remove cluster chain of the file. It reads to
a lost cluster of the FAT volume. This is added at a bugfix of R0.10c.
