[PULL 7/7] main loop: add missing documentation links to GS/IO macros

[Kevin Wolf]

From: Emanuele Giuseppe Esposito <eesposit@redhat.com>

If we go directly to GLOBAL_STATE_CODE, IO_CODE or IO_OR_GS_CODE
definition, we just find that they "mark and check that the function
is part of the {category} API".
However, ther is no definition on what {category} API is, they are
in include/block/block-*.h
Therefore, add a comment that refers to such documentation.
