Daniel Pieczko c577e59ed7 sfc: fully reset if MC_REBOOT event received without warm_boot_count increment 
On EF10, MC_CMD_VPORT_RECONFIGURE can cause a CODE_MC_REBOOT event
to be sent to a function without incrementing the (adapter-wide)
warm_boot_count.  In this case, the reboot is not detected by the
loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC
reboot anyway.  When this codepath is run, the MC has always just
rebooted, so this recovery is valid.

The loop on efx_mcdi_poll_reboot() is still required for other MC
reboot cases, so that actions in response to an MC reboot are
performed, such as clearing locally calculated statistics.
Siena NICs are unaffected by this change as the above scenario
does not apply.
