read_unlock - release reader lock. : handle to effective address of lock variable.

Description: Release a reader lock. The only restriction here is that must be word aligned.

Context: This routine should be used when interrupts do not need to be re-enabled --either because interrupts are not being used, or because the application will take steps to re-enable them later.
