Get status after current operation completes.
This function will issue a command to read out the status, and will then read the status continuously from the chip until it indicates that it is not busy. The error flag of the status is then checked, before returning the result.
| chip | Address of SerialFlash chip instance to operate on. |
| STATUS_OK | if operation succeeded. |
| STATUS_ERR_IO | if an error occurred. |
