Revert raidz_map and _col structure types

Browse Source 
As part of the refactoring of ab9f4b0b82,
several uint64_t-s and uint8_t-s were changed to other types.  This
caused ZoL github issue #6981, an overflow of a size_t on a 32-bit ARM
machine.  In absense of any strong motivation for the type changes, this
simply puts them back, modulo the changes accumulated for ABD.

Compile-tested on amd64 and run-tested on armhf.
