The EFI GUID in FreeBSD is layouted as following
typedef struct efi_guid {
uint32_t Data1;
uint16_t Data2;
uint16_t Data3;
uint8_t Data4[8];
} efi_guid_t;
Which means the Data1, Data2, Data3 should follows the little endian
rule as the MSB should be in the right side.
Also, the table_len in the ioctl argument of EFI_GET_TABLE should be
follow the uuid structure. Fix it by reorder it.
