nobh: nobh_write_end fix

This path mustn't have been tested :( I did attempt to exercise it
by injecting failures here, but I suspect PageMappedToDisk may have
been getting in the way. Will need more of a look, although I think
nobh mode is OK for an -rc1 (it shouldn't eat anyone's data).

Commit 03158cd7eb3374843de68421142ca5900df845d9 ("fs: restore nobh")
introcduced a NULL deref.  Spotted by the Coverity checker.
