Subject: [PATCH 5.13 159/800] crypto: ecdh - fix ecdh-nist-p192s entry in testmgr

From: Hui Tang <tanghui20@...wei.com>

[ Upstream commit 6889fc2104e5d20899b91e61daf07a7524b2010d ]

Add a comment that p192 will fail to register in FIPS mode.

Fix ecdh-nist-p192's entry in testmgr by removing the ifdefs
and not setting fips_allowed.
