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.
