Pengjie Zhang f103fa127c ACPI: PCC: Fix race condition by removing static qualifier ...

Local variable 'ret' in acpi_pcc_address_space_setup() is currently
declared as 'static'. This can lead to race conditions in a
multithreaded environment.

Remove the 'static' qualifier to ensure that 'ret' will be allocated
directly on the stack as a local variable.

Fixes: a10b1c99e2 ("ACPI: PCC: Setup PCC Opregion handler only if platform interrupt is available")
