A newly introduced function has 'const int' as the return type,
but as "make W=1" reports, that has no meaning:
drivers/md/dm-raid.c:510:18: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]
This changes the return type to plain 'int'.

Cherry-picked from 68c1c4d5eafc65dd ("dm raid: don't use 'const' in
function return") with new Fixes tag, as the issue has been
reintroduced.

function return") with
Fixes: 552aa679f2657431 ("dm raid: use rs_is_raid*()")

A newly introduced function has 'const int' as the return type,
but as "make W=1" reports, that has no meaning:
drivers/md/dm-raid.c:510:18: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]
This changes the return type to plain 'int'.
