    linux/probe-input: don't use error prio init
    
    it may happen in the out: case that LIBHAL_FREE_DBUS_ERROR (&error) is
    called before the error structure is initialized via
    dbus_error_init (&error). This could lead to a segfault during startup
    as seen in dmesg:
    
    |Intel AES-NI instructions are not detected.
    |padlock: VIA PadLock not detected.

    What I run into seems to be reported as Debian #562068 [0]. This patch
    makes the segfault go away on my machine.
