The function calls bitmap_or() immediately followed by bitmap_weight().
Switch to using the dedicated bitmap_weighted_or() and save one bitmap
traverse.

It's not entirely clear to me why this patch is included in a patchset
for the ice driver.

And it's also not clear to me why, but allmodconfigs - fo4 at least x86_32
and x86_64 - fail with this patch applied to net-next [1].

ERROR: modpost: "__bitmap_weighted_or" [drivers/gpu/drm/xe/xe.ko] undefined!

[1] 2b12ffb66955 ("net: mana: Trigger VF reset/recovery on health check failure due to HWC timeout")

I'm also seeing the same error and no apparent reason. Since this 
doesn't seem dependent on the others, I'll take the other 3 and this can 
get sent/resolved separately.

Thanks,
Tony
