 Close a file identified by the ''fd_id'' file descriptor.
 It decrements the reference count in the inode associated to the file, and release the fd_id entry in the file descriptors array.
 If the reference count is zero, it writes all dirty clusters on block device, and releases the memory allocated to the file_cache.
