CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS. It perhaps
was thought that it's needed for __crypto_xor, but that's not the case.
Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a
benchmark when it is initialized. That causes a boot time regression on
systems that didn't have it enabled before.
Therefore, remove this unnecessary and problematic selection.
