spi: spi-fsl-lpspi: remove redundant spi_controller_put call

devm_spi_alloc_controller will allocate an SPI controller and
automatically release a reference on it when dev is unbound from
its driver. It doesn't need to call spi_controller_put explicitly
to put the reference when lpspi driver failed initialization.
