Subject: UBI: fix check for "too many bytes"

From: Brian Norris <[email protected]>

commit 299d0c5b27346a77a0777c993372bf8777d4f2e5 upstream.

The comparison from the previous line seems to have been erroneously (partially) copied-and-pasted onto the next. The second line should be checking req.bytes, not req.lnum.
