[PATCH 1/1] wmc: Avoid uninitialized variable in init_argv0_dir

[Gerald Pfeifer]

From: Gerald Pfeifer

init_argv0_dir has conditional code for different operating systems. In
case of FreeBSD a variable remains uninitialized in the error case, yet
is then used. Fix that by handling the error case.
