sfc: protect list of RSS contexts under a mutex

Otherwise races are possible between ethtool ops and
 efx_ef10_rx_restore_rss_contexts().
Also, don't try to perform the restore on every reset, only after an MC
 reboot, otherwise we'll leak RSS contexts on the NIC.

Fixes: 42356d9a137b ("sfc: support RSS spreading of ethtool ntuple filters")
