  -----------
  Fix the return values of the aarch64 unroll8_eor_aes_gcm_*_*_kernel functions

These aren't currently checked when they are called in cipher_aes_gcm_hw_armv8.inc,
but they are declared as returning as size_t the number of bytes they have processed,
and the aes_gcm_*_*_kernel (unroll by 4) versions of these do return the correct
values.
