Subject: [for-next][PATCH 05/11] kdb: Remove fallback interpretation of arbitrary numbers as hex

From: Nir Lichtman <nir@...htman.org>

Remove logic that enables a fallback of interpreting numbers supplied in KDB CLI
to be interpreted as hex without explicit "0x" prefix as this can be confusing
for the end users.
