Fix comparison function in qt-models/divelocationmodel.cpp
The function dive_site_less_than() in qt-models/divelocationmodel.cpp
does not what it promises: it uses less-or-equal instead of less-than
comparison.
Note that, even though this may sound pedantic, this is an actual bug.
Usually, sorting functions suppose that they are provided with
strict weak ordering, which <= does *not* provide.
This is the actual reason for the crash mentioned in commit
f8a3a8521003a26525b658840ce8e7bfd3f7b141.
While touching this function, make it of static linkage, since
its usage is local to this translation unit.
