PCI: revert additional _OSC evaluation

PCI: revert additional _OSC evaluation

Reverts 80c0ccd0b575b26c57ef6b403102ed4261807c0e.

The commit 80c0ccd0b575b26c57ef6b403102ed4261807c0e was based on the
improper assumption that queried result was not updated when _OSC
support field was changed. But, in fact, queried result is updated
whenever _OSC support field was changed through __acpi_query_osc().
As a result, the commit 80c0ccd0b575b26c57ef6b403102ed4261807c0e only
introduced unnecessary additional _OSC evaluation...
