mlx4_core: Reset device when internal error is detected
Reset the device when an internal error is detected. Also, detect errors by polling the error buffer rather than using interrupts. This is more robust and doesn't depend on MSI-X. Remove the old interrupt handler entirely, since we don't want to support two mechanisms for detecting internal errors.
