spi: txx9: fix reference leak to master in txx9spi_remove()
Once a spi_master_get() call succeeds, we need an additional
spi_master_put() call to free the memory, otherwise we will
leak a reference to master. Fix by removing the unnecessary
spi_master_get() call.
Fixes: 2fe7e4add3e5 ('spi: txx9: use devm_spi_register_master()')
