crypto: adiantum - initialize crypto_spawn::inst
crypto_grab_*() doesn't set crypto_spawn::inst, so templates must set it
beforehand. Otherwise it will be left NULL, which causes a crash in
certain cases where algorithms are dynamically loaded/unloaded. E.g.
with CONFIG_CRYPTO_CHACHA20_X86_64=m, the following caused a crash:
insmod chacha-x86_64.ko
python -c 'import socket; socket.socket(socket.AF_ALG, 5, 0).bind(("skcipher", "adiantum(xchacha12,aes)"))'
rmmod chacha-x86_64.ko
python -c 'import socket; socket.socket(socket.AF_ALG, 5, 0).bind(("skcipher", "adiantum(xchacha12,aes)"))'
Fixes: 059c2a4d8e16 ("crypto: adiantum - add Adiantum support")
