[ Upstream commit 551d793f65364c904921ac168d4b4028bb51be69 ]
When reading the PPAG table from ACPI, we should store everything in
our fwrt structure, so it can be accessed later. But we had a local
ppag_table variable in the function and were erroneously storing the
enabled/disabled flag in it instead of storing it in the fwrt. Fix
this by removing the local variable and storing everything directly in
fwrt.
