IB/core: When marshaling ucma path from user-space, clear unused fields
commit c2be9dc0e0fa59cc43c2c7084fc42b430809a0fe upstream.
When marshaling a user path to the kernel struct ib_sa_path, we need
to zero smac and dmac and set the vlan id to the "no vlan" value.
This is to ensure that Ethernet attributes are not used with
InfiniBand QPs.
Fixes: dd5f03beb4f7 ("IB/core: Ethernet L2 attributes in verbs/cm structures")
