Symptoms:
	PHKL_26104:
	( SR:8606222333 CR:JAGad91448 )
	If the VX_FREEZE ioctl(2) syscall is called with an invalid
	timeout value then subsequently called with a proper value
	the ioctl(2) call does not return for almost two minutes
	and any other operations (ls, etc) are blocked.

Defect Description:
	PHKL_26104:
	( SR:8606222333 CR:JAGad91448 )
	If ioctl(.. ,VX_FREEZE, ..) is called with an invalid
	argument(timeout value) and then is subsequently called
	with a valid argument, the timeout value doesn't work
	correctly. The ioctl(2) call will not return for about
	two minutes and when it does all disk access operations
	(ls, etc) to the disk are blocked.

	The failure occurs because the timeout value argument
	check, in the ioctl(2) call, does not occur early enough
	in the code path.

	Resolution:
	The timeout value argument check was moved ahead of the
	VX_FREEZE code path. This assures that no code releted to
	VX_FREEZE is executed until the timeout value has been
	validated. If an incorrect argument is supplied and error
	indicating an invalid argument (EINVAL) is returned.
