riscv: KVM: Fix hart suspend_type use
[ Upstream commit e3219b0c491f2aa0e0b200a39d3352ab05cdda96 ]
The spec says suspend_type is 32 bits wide and "In case the data is
defined as 32bit wide, higher privilege software must ensure that it
only uses 32 bit data." Mask off upper bits of suspend_type before
using it.
