snep-validation: Fix compilation on ARM due to unaligned memory access

Use near_get_be32 helper function to access nfc_data. Although there is
most likely no risk of unaligned access since nfc_data is allocated
from heap (and properly alligned as access starts from first byte) this
result in compilation error on ARM (Debian GCC 4.6.3).
