hog: Remove pre-existing suspend FIFO
hog: Remove pre-existing suspend FIFO

If bluetoothd crashes the exit routine of the suspend plugin will not be
executed, leaving the suspend FIFO behind and preventing the plugin load
on subsequent executions. This commit checks for pre-existence of the
suspend FIFO and tries to remove and re-create it.
