MdeModulePkg/Spi: Allow NULL WriteBuffer in FillWriteBuffer()
Fix false positive assert added in #10924
Functon `FillWriteBuffer()` should able to accept NULL WriteBuffer when
WriteBytes equals 0.
Use case:
```
// Read Status register
TransactionBufferLength = FillWriteBuffer (
Instance,
SPI_FLASH_RDSR,
SPI_FLASH_RDSR_DUMMY,
SPI_FLASH_RDSR_ADDR_BYTES,
FALSE,
0,
0, // WriteBytes = 0
NULL // WriteBuffer can be NULL
);
```
