[ Upstream commit 70facbf978ac90c6da17a3de2a8dd111b06f1bac ]
Previously, the condition for invalidating the tx flow in mctp_i2c_invalidate_tx_flow() checked if `rc` was nonzero. However, this could incorrectly trigger the invalidation even when `rc > 0` was returned as a success status.
This patch updates the condition to explicitly check for `rc < 0`, ensuring that only error cases trigger the invalidation.
