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by gfs2 for internals reads, but this use of the interface was rather suboptimal (as was the whole interface) and has been replaced by an internal helper now.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.
