The ext interrupts are enabled when the firmware has been started, but
this may never happen, for example, if the board configuration file is
missing.

When the system is later suspended, the driver unconditionally tries to
disable interrupts, which results in an irq disable imbalance and causes
the driver to spin indefinitely in napi_synchronize().

Make sure that the interrupts have been enabled before attempting to
disable them.
