IB/opa_vnic: Use GFP_ATOMIC while sending trap
Pass GFP_ATOMIC flag to ib_create_send_mad() while sending trap as it
can be triggered from the atomic context.
Fix the following trace with debug kernel.
BUG: sleeping function called from invalid context at mm/slab.h:432
in_atomic(): 1, irqs_disabled(): 0, pid: 1771, name: NetworkManager
