commit969e2f59d5upstream. Commit5092fcf349("crypto: arm64/aes-ce-ccm: add non-SIMD generic fallback") introduced C fallback code to replace the NEON routines when invoked from a context where the NEON is not available (i.e., from the context of a softirq taken while the NEON is already being used in kernel process context) Fix two logical flaws in the MAC calculation of the associated data.
