ACPI: fix Medion _PRT quirk (use "ISA_", not "ISA")

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop.  The
BIOS reports the interrupt routing incorrectly.  I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.

We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything.  We need ".ISA_." instead.

Thank you Johann-Nikolaus Andreae <[email protected]>
for patiently testing this patch.
