crypto: lib - remove unneeded selection of XOR_BLOCKS 



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.
