kvm: Fix CR3_PCID_INVD type on 32-bit
arch/x86/kvm/emulate.c: In function ‘check_cr_write’:
arch/x86/kvm/emulate.c:3552:4: warning: left shift count >= width of type
rsvd = CR3_L_MODE_RESERVED_BITS & ~CR3_PCID_INVD;
happens because sizeof(UL) on 32-bit is 4 bytes but we shift it 63 bits
to the left.
