crypto: aead - pass instance to crypto_grab_aead()
Initializing a crypto_aead_spawn currently requires:
1. Set spawn->base.inst to point to the instance.
2. Call crypto_grab_aead().
But there's no reason for these steps to be separate, and in fact this
unneeded complication has caused at least one bug, the one fixed by
commit 4155904c1677 ("crypto: adiantum - initialize crypto_spawn::inst")
So just make crypto_grab_aead() take the instance as an argument.
To keep the function calls from getting too unwieldy due to this extra
argument, also introduce a 'mask' variable into the affected places
which weren't already using one.
