spi: spi-fsl-lpspi: Reset FIFO and disable module on transfer abort

In DMA mode fsl_lpspi_reset() is always called at the end, even when the
transfer is aborted. In PIO mode aborts skip the reset leaving the FIFO
filled and the module enabled.

Fix it by always calling fsl_lpspi_reset().

Fixes: a15dc3d657fa ("spi: lpspi: Fix CLK pin becomes low before one transfer")
