sfc: return a better error if filter insertion collides with MC reboot If some other operation gets the MCDI lock ahead of us and performs an MC reboot, then our attempt to insert the filter will fail with EINVAL, because the destination VI (spec->dmaq_id, MC_CMD_FILTER_OP_IN_RX_QUEUE) does not exist. But the caller's request (which might e.g. be an ethtool ntuple request from userland) isn't invalid, it just got unlucky; so return EAGAIN.
