crypto: lib/chacha20poly1305 - Set SG_MITER_ATOMIC unconditionally
There is no reason for the chacha20poly1305 SG miter code to use
kmap instead of kmap_atomic as the critical section doesn't sleep
anyway. So we can simply get rid of the preemptible check and
set SG_MITER_ATOMIC unconditionally.
Even if we need to reenable preemption to lower latency we should
be doing that by interrupting the SG miter walk rather than using
kmap.
