/drivers/mtd/mtdblock_ro.c is buggy

["Callebaut, Benoît"]

Hi everybody,
After a lot of debugging I seen that there is a bug in the MTD read only
block driver.
It seems that in the mtdblock_request, something goes wrong withe the
handling of the request structure.
between two calls to end_request, the pointer bh->req_qnext of the last used
buffer head is corrupted.
I didn't find the cause but since this happens only with the
mtdblock_request function I suppose there is something wrong in it.

If I ever find what's wrong I will try to correct it, but don't hope too
much I don't have a lot of time.
