sfc: take correct lock in ef100_reset()
When downing and upping the ef100 filter table, we need to take a write
lock on efx->filter_sem, not just a read lock, because we may kfree()
the table pointers.
Without this, resets cause a WARN_ON from efx_rwsem_assert_write_locked().
Fixes: a9dc3d5612ce ("sfc_ef100: RX filter table management and related gubbins")
