By accident I stumbled across code that has never been used. This
driver has EXPORT_SYMBOL functions, and the only user of the code is
pcrypt.c, but this only uses a subset of the exported symbols.
According to 'git log -G', the functions, padata_set_cpumasks,
padata_add_cpu, and padata_remove_cpu have never been used since they
were first introduced. This patch removes the unused code.
On one 64 bit build, with CRYPTO_PCRYPT built in, the text is more than
4k smaller.

On another config, 32 bit, the saving is about 0.5k bytes.
