ACPI: Pass the same capabilities to the _OSC regardless of the query flag

Commit 719e1f56 ("ACPI: Execute platform _OSC also with query bit
clear") makes acpi_bus_osc_negotiate_platform_control() not only query
the platforms capabilities but it also commits the result back to the
firmware to report which capabilities are supported by the OS back to
the firmware

On certain systems the BIOS loads SSDT tables dynamically based on the
capabilities the OS claims to support. However, on these systems the
_OSC actually clears some of the bits (under certain conditions) so what
happens is that now when we call the _OSC twice the second time we pass
the cleared values and that results errors like below to appear on the
system log:

  ACPI BIOS Error (bug): Could not resolve symbol [\_PR.PR00._CPC], AE_NOT_FOUND (20210105/psargs-330)
  ACPI Error: Aborting method \_PR.PR01._CPC due to previous error (AE_NOT_FOUND) (20210105/psparse-529)

In addition the ACPI 6.4 spec says following [1]:

  If the OS declares support of a feature in the Support Field in one
  call to _OSC, then it must preserve the set state of that bit
  (declaring support for that feature) in all subsequent calls.

Based on the above we can fix the issue by passing the same set of
capabilities to the platform wide _OSC in both calls regardless of the
query flag.

While there drop the context.ret.length checks which were wrong to begin
with (as the length is number of bytes not elements). This is already
checked in acpi_run_osc() that also returns an error in that case.
