The array's type should be given as the proper
DBUS_TYPE_STRING_AS_STRING, but evidently it
doesn't matter since it's all packed into a
variant type.

The perror() calls do not make much sense with libdbus functions and
wpa_printf() would really be used for all error printing anyway. In
addition, many of the error messages on out-of-memory cases are not
really of much use, so they were removed. This is also cleaning up
some of the error path handling to avoid duplicated code.
