hwmon/aspeed-pwm-tacho: Return 0 RPM if fan disconnected / failed
Having a tachometer read return an -ETIMEDOUT error condition
instead of 0 RPM due to a disconnected or failed fan is highly
unexpected, and depending on higher level software can cause
application failures.
Return 0 RPM if tachometer cannot be read. This should trigger
the same error paths in any sane fan control implementation without
requiring special handling for the AST2x00 devices.
