crypto: omap-aes - Fix support for unequal lengths
commit 6d7e7e02a044025237b6f62a20521170b794537f upstream.
For cases where total length of an input SGs is not same as
length of the input data for encryption, omap-aes driver
crashes. This happens in the case when IPsec is trying to use
omap-aes driver.
To avoid this, we copy all the pages from the input SG list
into a contiguous buffer and prepare a single element SG list
for this buffer with length as the total bytes to crypt, which is
similar thing that is done in case of unaligned lengths.
Fixes: 6242332ff2f3 ("crypto: omap-aes - Add support for cases of unaligned lengths")
