sif: Redefine IB_QP_CREATE_ flags

Redefine sif-spesific IB_QP_CREATE_ flags to avoid conflict with flags defined in ib_verbs.h
Flags moved to range defined by IB_QP_CREATE_RESERVED_START and IB_QP_CREATE_RESERVED_END

Note that we define more flags than fit the range and that some are defined below _RESERVED_START.
