[PATCH] fs: inode: return proper errno on bmap()

[Leesoo Ahn]

It better returns -EOPNOTSUPP instead of -EINVAL which has meaning of
the argument is an inappropriate value. It doesn't make sense in the
case of that a file system doesn't support bmap operation.

-EINVAL could make confusion in the userspace perspective.
