[PATCH v1] examples/fips_validation: fix memory leak in sha test

[Gowrishankar Muthukrishnan <gmuthukrishn@marvell.com>]

There is wrong size used for allocation of digest buffer which in
some cases cause memory corruption. Also, fixed places where memory
leak is observed.

Fixes: 93d797d94f1 ("examples/fips_validation: add parsing for sha")
