[PATCH] acpi: crsdump: fix portability warning from cppcheck

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

cppcheck detected an implementation defined behaviour issue,
fix this by making 1 an unsigned integer value before shifing
it.

src/acpi/crsdump/crsdump.c:321:17: portability: Shifting signed
32-bit value by 31 bits is implementation-defined behaviour
