Move iop->offset to the file systems.

This patch moves the iop->offset to the file systems. If the file system
manages locking such as DOSFS and RFS the operation is safe. For others the
race condition is still present.

This will not be solved in this PR and requires a higher level lock for the
whole operation. The move is still valid if we finally decide to have iop
locking configurable.
