x86/vm86: Make sure the free_vm86(task) definition uses its parameter even in the !CONFIG_VM86 case
I ran into a case in new code where free_vm86(task) was the only
consumer of the 'task' variable:
arch/x86/kernel/process.c: In function ‘exit_thread’:
arch/x86/kernel/process.c:118:31: error: unused variable ‘t’ [-Werror=unused-variable]
Robustify the definition in the !CONFIG_VM86 case.
