The write buffer may not have been written and may no longer be written
due to an interrupted write in the affected page.

Dan Carpenter ccf31c10f1 logfs: handle errors from get_mtd_device() 
The get_mtd_device() function returns error pointers on failure and if we
don't handle it, it leads to a crash.

Joern Engel 9421502b4f [LogFS] Fix bdev erases 
Erases for block devices were always just emulated by writing 0xff.
Some time back the write was removed and only the page cache was
changed to 0xff.  Superficialy a good idea with two problems:
1. Touching the page cache isn't necessary either.
2. However, writing out 0xff _is_ necessary for the journal.  As the
   journal is scanned linearly, an old non-overwritten commit entry
   can be used on next mount and cause havoc.

This should fix both aspects.
