All RDMA drivers except ehca set class_dev->dev to their dma_device
value (ehca leaves this unset).  dma_device is the only value that
makes any sense, so move this assignment to core/sysfs.c.  This reduce
the duplicated code in the rest of the drivers and gives ehca a nice
/sys/class/infiniband/ehcaX/device symlink.

Rework some load-time error handling: c2_register_device() leaked when
it failed, and the function that called it didn't check the return code.

If the allocation of mr fails, then c2_reg_phys_mr() leaks the
page_list array it allocated earlier.

indirect chains of includes are arch-specific and can't
be relied upon...  (hell, even attempt to build it for
itanic would trigger vmalloc.h ones; err.h triggers
on e.g. alpha).
