Subject: ocfs2: acknowledge return value of ocfs2_error()

Caveat: This may return -EROFS for a read case, which seems wrong.  This
is happening even without this patch series though.  Should we convert
EROFS to EIO?

I must be doing something wrong because in the kernels I've looked at,
ocfs2_error() is a void function.

Well I realized that the error was mine and I missed this patch,

The preceding patch (ocfs2: add errors=continue) changed the
ocfs2_error() return type.
