hwmon: (mcp9982) Propagate one-shot polling errors
When a device is in standby, the driver starts a one-shot conversion and
polls the BUSY flag before reading temperature, alarm, or fault data.
The poll result is currently ignored. Therefore, a timeout or a
status-register read failure can be hidden by a later successful read,
causing stale data to be returned as valid.
Return the polling error before reading the requested attribute.
Fixes: e2fe950f34e5 ("hwmon: add support for MCP998X")
