equipment: sanitize 'ws_info' loop limits

Browse source 
Instead of a constant or a macro for the maximum
number of 'ws_info' elements the 100 literal was used.

Define MAX_WS_INFO in dive.h and use it everywhere.

Also clamp loops that iterate `ws_info' to MAX_WS_INFO.
Prevents potential out-of-bounds reading, similarly to
the previous commit about 'tank_info'.
