features/marker-quota: more stringent error handling in rename.
If an error occurs and op_errno is not set to non-zero value, we can
end up in loosing a frame resulting in a hung syscall. This patch
adds code setting op_errno appropriately in storage/posix and
makes marker to set err to a default non-zero value in case of
op_errno being zero.
