kill do_generic_mapping_read

do_generic_mapping_read was used by gfs2 for internals reads, but this use
of the interface was rather suboptimal (as was the whole interface) and has
been replaced by an internal helper now.  This patch kills
do_generic_mapping_read and surrounding damage in preparation of additional
cleanups for the buffered read path.
