pds_core: remove redundant pci_clear_master()

do_pci_disable_device() disable PCI bus-mastering as following:
static void do_pci_disable_device(struct pci_dev *dev)
{
		u16 pci_command;

		pci_read_config_word(dev, PCI_COMMAND, &pci_command);
		if (pci_command & PCI_COMMAND_MASTER) {
				pci_command &= ~PCI_COMMAND_MASTER;
				pci_write_config_word(dev, PCI_COMMAND, pci_command);
		}

		pcibios_disable_device(dev);
}
And pci_disable_device() sets dev->is_busmaster to 0.

pci_enable_device() is called only once before calling to
pci_disable_device() and such pci_clear_master() is not needed. So remove
redundant pci_clear_master().

Also rename goto label 'err_out_clear_master' to 'err_out_disable_device'.
