x86: use symbolic name for VM86_SIGNAL when used as vm86 default return
This code has apparently used "0" and not VM86_SIGNAL since Linux 1.1.9, when Linus added VM86_SIGNAL to vm86.h. This patch changes the code to use the symbolic name. The magic 0 tripped me up in trying to extend the vm86(2) manpage to actually explain vm86()'s interface -- my greps for VM86_SIGNAL came up fruitless.
