[PATCH v1] examples/fips_validation: fix digest length in AES GCM

[Samina Arshad <samina.arshad@intel.com>]

For AES GCM non JSON decrypt test cases the digest length
is being set incorrectly.The digest length is not being
cleared after test cases, causing an issue when running
tests individually without the --path-is-folder flag.
This fix adds the digest length correctly to the decrypt
cases and clears the digest length after each test file.
