spi: spi-mt65xx: Fix NULL pointer access in interrupt handler
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: 1ce24864bff4 ("spi: mediatek: Only do dma for 4-byte aligned buffers")
