crypto: tcrypt - fix return value for multiple subtests

Browse source

[ Upstream commit 65c92cbb3f ]

When a test mode invokes multiple tests (e.g., mode 0 invokes modes
1 through 199, and mode 3 tests three block cipher modes with des),
don't keep accumulating the return values with ret += tcrypt_test(),
which results in a bogus value if more than one report a nonzero
value (e.g., two reporting -2 (-ENOENT) end up reporting -4 (-EINTR)).
Instead, keep track of the minimum return value reported by any
subtest.
