[PATCH 1/1] PCI/IDE: Fix reading a wrong reg for unused sel stream initialization

[Li Ming]

During pci_ide_init(), it will write PCI_ID_RESERVED_STREAM_ID into all
unused selective IDE stream blocks. In a selective IDE stream block, IDE
stream ID field is in selective IDE stream control register instead of
selective IDE stream capability register.

Fixes: 079115370d00 ("PCI/IDE: Initialize an ID for all IDE streams")
