crypto: hisilicon/sec2 - Use atomics instead of __sync

The use of __sync functions for atomic memory access is not
supported in the kernel, and can result in a link error depending
on configuration:

ERROR: "__tsan_atomic32_compare_exchange_strong" [drivers/crypto/hisilicon/sec2/hisi_sec2.ko] undefined!
ERROR: "__tsan_atomic64_fetch_add" [drivers/crypto/hisilicon/sec2/hisi_sec2.ko] undefined!

Use the kernel's own atomic interfaces instead. This way the
debugfs interface actually reads the counter atomically.
