ext4: Convert BUG_ON checks to use ext4_error() instead
Convert a bunch of BUG_ONs to emit a ext4_error() message and return EIO. This is a first pass and most notably does _not_ cover mballoc.c, which is a morass of void functions. Signed-off-by: Frank Mayhar <fmayhar@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
