Some of the report_*() functions are internal and will be declared static,
and their declaration removed from rtw_mlme_ext.h, in a later commit.
This would break compilation, since they are are referenced before their
definition.
Reorder these functions so that symbols are defined before they are
referenced, without the need for forward declarations.
Also move near the beginning of the file the collect_bss_info() and
process_80211d(), since they are called from the report_*() functions.
This commit only reorders code, there is no content change.
