btl/ofi: Use internal macros for FI_MR_BASIC and FI_MR_SCALABLE

FI_MR_BASIC (1<<0) and FI_MR_SCALABLE (1<<1) are deprecated
since Libfabric 1.5 and the symbols will get removed in
future Libfabric 2.x versions. Use the internal mode bits
for backward compatibilities without breaking compilation
with newer libfabric.
