cnic, bnx2: Check iSCSI support early in bnx2_init_one()
commit 7625eb2f2fff7bfae41d3119b472c20b48874895 upstream.
Based on earlier patch from Neil Horman <nhorman@tuxdriver.com>
If iSCSI is not supported on a bnx2 device, bnx2_cnic_probe() will
return NULL and the cnic device will not be visible to bnx2i. This
will prevent bnx2i from registering and then unregistering during
cnic_start() and cause the warning message:
bnx2 0003:01:00.1: eth1: Failed waiting for ULP up call to complete
