This reverts commit 97be116a39fee62b8f7027fd93d93789a6d04abb.
This commit broke nxffs. This leaves the first block as empty which
then exposes another bug where when the pack is called because we
have reached the end of flash and need to look for deleted inodes
we search the first block find no inode and assume that there
are no more inodes. This then results in corrupting the filesystem
by writing over existing inodes.
This can be seen by runing the sim:nxffs configuration.
Prior to this commit the first pass of writing files would look like
this:

The unique minor limit of 255 will overflow easily in
some scenarios where eventfd needs to be create/destroy
frequently:
while (1)
{
fd = eventfd(0, 0); // minor++
sleep(1);
close(fd);
}
remove the unique minor limit.

There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

because:
1.The name of directory may terminated by the whitespace
2.inode_search can handle the trailing '/' correctly
3.Let fix the issue in FAT filesystem instead
This reverts commit 97b0235d77ff4ee7c8eb5288b2a001a1d12bf707.
1.Reduce the default size of task_group_s(~512B each task)
2.Scale better between simple and complex application
