dm raid: fix discard support regression
commit
11e2968478edc07a75ee1efb45011b3033c621c2 upstream.
Commit
ecbfb9f118 ("dm raid: add raid level takeover support") moved the
configure_discard_support() call from raid_ctr() to raid_preresume().
Enabling/disabling discard _must_ happen during table load (through the
.ctr hook). Fix this regression by moving the
configure_discard_support() call back to raid_ctr().
