RDMA/erdma: restrict the driver to little-endian systems

The eRDMA device interface requires explicit byte ordering, but several
DMA-visible values that should be little-endian remain native-endian.
Command request payloads are copied verbatim, data-path SQE headers are
written without cpu_to_le64(), and kernel doorbell records are assigned
plain u64 values. The command completion path also reads a little-endian
SQE header without conversion.

These paths are byte-swapped on big-endian kernels and can break command
processing during probe. Since complete big-endian support requires
converting every device-visible structure, depend on !CPU_BIG_ENDIAN.
