[PATCH] __bread oops fix
If a filesystem passes an idiotic blocksize into bread(), __getblk_slow() will
warn and will return NULL. We have a report (from Hubert Tonneau
<hubert.tonneau@fullpliant.org>) of isofs_fill_super() doing this (passing in
a silly block size) against an unplugged CDROM drive.
But a couple of __getblk_slow() callers forgot to check for the NULL bh, hence
oops.
