lib/crypto: arm64/aes: Remove obsolete chunking logic
Since commit aefbab8e77eb ("arm64: fpsimd: Preserve/restore kernel mode
NEON at context switch"), kernel-mode NEON sections have been
preemptible on arm64. And since commit 7dadeaa6e851 ("sched: Further
restrict the preemption modes"), voluntary preemption is no longer
supported on arm64 either. Therefore, there's no longer any need to
limit the length of kernel-mode NEON sections on arm64.
Simplify the AES-CBC-MAC code accordingly.
