[PATCH 4/9] divelogexportdialog.cpp: fix a 'uninitialized variable' warning

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

DiveLogExportDialog::export_depths()

We set a default value of 'unit' which will silence the warning itself.
Then hope that the compiler will respect the argument order i.e. call
get_depth_units() (which sets 'unit') before using *unit as the last
argument passsed to put_format().
