Subject: [PATCH 5.9 127/252] IB/hfi1: Fix error return code in hfi1_init_dd()

From: Zhang Changzhong <zhangchangzhong@...wei.com>

[ Upstream commit dabbd6abcdbeb1358a53ec28a244429320eb0e3a ]

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.

Fixes: 4730f4a6c6b2 ("IB/hfi1: Activate the dummy netdev")
