crypto: algapi - Remove unneeded null check
We don't check "frontend" consistently in crypto_init_spawn2(). We
check it at the start of the function but then we dereference it
unconditionally in the parameter list when we call crypto_init_spawn().
I looked at the places that call crypto_init_spawn2() and "frontend" is
always a valid pointer so I removed the check for null.
