Subject: [PATCH v1 1/1] RDMA/mana_ib: Fix compilation error

The compilation with CONFIG_WERROR=y is broken:

../hw/mana/device.c:88:6: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
	if (!upper_ndev) {
	    ^~~~~~~~~~~

Fix this by assigning the ret to -ENODEV in respective condition.

Fixes: 8b184e4f1c32 ("RDMA/mana_ib: Enable RoCE on port 1")
