Fei Shao 766ec94cc5 spi: spi-mt65xx: Fix NULL pointer access in interrupt handler 
[ Upstream commit a20ad45008 ]

The TX buffer in spi_transfer can be a NULL pointer, so the interrupt
handler may end up writing to the invalid memory and cause crashes.

Add a check to trans->tx_buf before using it.

Fixes: 1ce24864bf ("spi: mediatek: Only do dma for 4-byte aligned buffers")
