Don Hiatt 4988be5813 IB/hfi1: Do not warn on lid conversions for OPA 
On OPA devices opa_local_smp_check will receive 32Bit LIDs when the LID
is Extended. In such cases, it is okay to lose the upper 16 bits of the
LID as this information is obtained elsewhere. Do not issue a warning
when calling ib_lid_cpu16() in this case by masking out the upper 16Bits.
