staging: fbtft: do not allocate huge txbuf

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.
