When nxffs_mediacheck is called on block 0 and the filesystem looks like
this, it will fail thinking that there are no inodes. This is not correct. It
kind of looks like `nxffs_nextentry` is hitting that empty space and not
looking far enough to see block 1 before giving up and saying the rest of the
flash must be zero.
```
NXFFS Dump:
BLOCK:OFFS TYPE STATE LENGTH
0:0 BLOCK ERASED 512
1:5 INODE DELETED 6394
1:39 DATA OK 463
2:5 DATA OK 497
3:5 DATA OK 497
4:5 DATA OK 497
5:5 DATA OK 497
6:5 DATA OK 497
7:5 DATA OK 497
8:5 DATA OK 497
9:5 DATA OK 497
10:5 DATA OK 497
11:5 DATA OK 497
12:5 DATA OK 497
13:5 DATA OK 464
13:479 INODE DELETED 339
```
If I force `nxffs_mediacheck` to start at block 1 instead of 0 this will
pass.
