Add support for MR pages larger than 4K on eHCA2. This reduces
firmware memory consumption. If enabled via the mr_largepage module
parameter, the MR page size will be determined based on the MR length
and the hardware capabilities -- if the MR is >= 16M, 16M pages are
used, for example.

Instead of one error mapping function for each potential error source
in ehca_mrmw.c, use a centralized function that handles all cases,
saving a three-figure line count.
