[PATCH][next] selftests: kvm: fix shift of 32 bit unsigned int more than 32 bits

[Colin Ian King]

Currrentl a 32 bit 1u value is being shifted more than 32 bits causing
overflow and incorrect checking of bits 32-63. Fix this by using the
BIT_ULL macro for shifting bits.

Detected by cppcheck:
sev_init2_tests.c:108:34: error: Shifting 32-bit value by 63 bits is
undefined behaviour [shiftTooManyBits]

Fixes: dfc083a181ba ("selftests: kvm: add tests for KVM_SEV_INIT2")
