The pointer `Instance->SfdpBasicFlash` can be used before initializing.
Example code flow:
- CreateSpiNorFlashSfdpInstance: Allocate pool for `Instance`
- InitialSpiNorFlashSfdpInstance
- ReadSfdp
- ReadSfdpHeader
- FillWriteBuffer: Dereferencing
`Instance->SfdpBasicFlash`
- ReadSfdpBasicParameterTable: Allocate pool for
`Instance->SfdpBasicFlash`
Check both `Instance` and `Instance->SfdpBasicFlash` should have
a non null value before dereferencing it. Otherwise use the defaut
value 0.
Also terminate the function if `Instance` or `WriteBuffer` is NULL.
