This should make writing and reading more reliable.

We've had problems writing (and even reading) a 10 MiB file from barebox
to multiple USB flash drives.
The 10 MiB file copy failed with "write: I/O error" almost every time.
Increasing the retry count made 100 MiB file copies succeed every time.
Doing this doesn't hurt, so I applied this patch. I wonder though if
there's something else wrong which makes increasing the retry counts
necessary.

Thanks, yes, so I thought, too; it doesn't hurt, so I sent it in.
From when I looked at the problem, it seemed to me that the whole USB
flash drives thing is fickle. I glanced at the USB storage drivers of
Linux and saw that they have a bunch of workarounds and per-device
quirks. So Linux' drivers simply seem more mature and tolerant than
those in barebox.
