AArch64: Revert previous branch optimization

Revert a branch optimization that was based on an incorrect
assumption in the AArch64 part of ZSTD_decodeSequence. In extreme
cases the existing implementation could lead to data corruption.

Insert an UNLIKELY hint to guide the compilers toward generating more
efficient machine code.
