Use falloc_noinstall + finstall.

Test Plan

• cryptocheck still passes ok

I guess this race doesn't really matter as if you try to use the file before finit() you just get badfileops and finit() itself is "atomic"? If so, I could just leave this as-is unless this approach is preferred.

No objection, but I believe you're correct about finit() being "atomic." (I mean, it is atomic. But are the fops consumers?)

sys/opencrypto/cryptodev.c

Will the compiler complain about storing fd to a uint32_t lvalue? I guess that part has not changed, so no.
