From: Hardevsinh Palaniya <hardevsinh.palan...@siliconsignals.io>
[ Upstream commit 7dd9eb6ba88964b091b89855ce7d2a12405013af ]
The original code checks 'if (ARC_CC_AL)', which is always true since
ARC_CC_AL is a constant. This makes the check redundant and likely
obscures the intention of verifying whether the jump is conditional.
Updates the code to check cond == ARC_CC_AL instead, reflecting the intent
to differentiate conditional from unconditional jumps.
