Don Hiatt 6588e412fe IB/core: Do not warn on lid conversions for OPA 
On OPA devices the user_mad recv_handler can receive 32Bit LIDs
(e.g. OPA_PERMISSIVE_LID) and 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_be16() in this case by masking out
the upper 16Bits.
