[PATCH 1/1] powerpc/crypto: Add cond_resched() in crc-vpmsum self-test

[Chris Smart]

The stress test for vpmsum implementations executes a long for loop in
the kernel. This blocks the scheduler, which prevents other tasks from
running, resulting in a warning.

This fix adds a call to cond_reshed() at the end of each loop, which
allows the scheduler to run other tasks as required.
