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.
