megha.dey@linux.intel.com 8861249c74 crypto: x86/sha1 - Fix reads beyond the number of blocks passed 
It was reported that the sha1 AVX2 function(sha1_transform_avx2) is
reading ahead beyond its intended data, and causing a crash if the next
block is beyond page boundary:
http://marc.info/?l=linux-crypto-vger&m=149373371023377

This patch makes sure that there is no overflow for any buffer length.

It passes the tests written by Jan Stancek that revealed this problem:
https://github.com/jstancek/sha1-avx2-crash

I have re-enabled sha1-avx2 by reverting commit
b82ce24426

Cc: <stable@vger.kernel.org>
Fixes: b82ce24426 ("crypto: sha1-ssse3 - Disable avx2")
