sm_down is a boolean in order to check if the internal switch of the
fm10k is up or down. This variable is configured though an interrupt by
fm10k_dev_interrupt_handler_pf.
If sm_down is uninitialized, we are not sure of its value at the first
bring up. For example, if FM10K_EICR_SWITCHREADY is raised, the PMD will
try to reconfigure the switch, but it does not make sense, as it's the
first startup.
The sm_down implementation has been introduced
