PATCH 1/1 ACPI: processor: idle: Drop unnecessary statements and parens

From: Rafael J. Wysocki <[email protected]>

Drop a redundant "else", a "return" statement at the end of a void function and redundant parentheses around an unsigent int variable name from the ACPI processor idle driver.

No expected functional impact.
