txbuflen can be set to arbitrary value by user and it is also set
automagically to the maximum transfer size of the SPI master controller.
Do not allocate the buffer when larger than vmem. When my SPI master
controller reports maximum transfer size 16M the probe of fbtft fails.

Unnecessary spi_set_drvdata() has been removed since the driver
core clears the driver data to NULL after device release or on
probe failure. There is no need to manually clear the device
driver data to NULL.
The Coccinelle semantic patch used to make this change is as follows:
@@
struct spi_device *spi;
@@
- spi_set_drvdata(spi, NULL);
// </smpl>
Due to this removal, variable `spi` was unused so dropped `spi`
